Quick answer: a sand suction rubber hose runs roughly $9 to $95 per metre FOB China in 2026, depending almost entirely on bore size and how it is built. A 6″ suction hose in a standard 2–3 ply SBR build lands near $14–$24/m; a 12″ hose in a 4-ply natural rubber build with stainless flanges pushes $36–$58/m; and a self-floating 16″ suction line can clear $90/m. Anything quoted under $7/m for a “sand suction hose” is almost always a water hose with a dredging label — it will collapse the first time the pump pulls a hard vacuum.
This is the suction-side guide. Suction hose is not the same product as discharge hose, and it is not priced the same way — the suction side carries vacuum, so its reinforcement is built to resist collapse, not just burst. If you are still deciding between the two, SRH and DRH are not interchangeable, and the difference shows up directly in the quote.
What a sand suction rubber hose actually is
A sand suction rubber hose (often called an SRH, or simply a dredge suction hose) is the flexible section that connects a dredge pump — or a suction excavator, or a sand ladder — to the intake on the riverbed or seabed. It has to bend with the motion of the floating line, survive being dragged across stone, and resist the constant inward pull of the pump’s suction.
That last part is the whole engineering problem. On the discharge side, pressure pushes outward, so the hose is built to not burst. On the suction side, the pump pulls a vacuum, so the hose is built to not collapse. A hose that collapses starves the pump, cavitates the impeller, and in the worst case folds shut mid-run. That is why every sand suction hose has a helical wire in the wall — the helix is what holds the bore open against the vacuum. The helix, not the rubber, is the single most important part of a suction hose, and it is the first thing a cheap quote quietly leaves thin.

The 7 variables that decide the price
Two quotations for “10 inch sand suction hose” can differ by 5×. Every legitimate one is a combination of the seven variables below. Once you can name them, a quote stops being a number and becomes a specification you can compare.
Variable 1 — Inner diameter
Price does not scale linearly with bore. A 12″ suction hose costs roughly 90–120% more than an 8″, not 50% more, because larger bores need thicker walls to resist collapse, a heavier helix wire, and stronger end fittings — the axial load at the flange grows with the square of the diameter. At 1.0 MPa a DN200 flange sees about 50 kN of end load; a DN400 at the same rating sees about 200 kN. The flange, not the rubber, is where the money goes on big bores.
Variable 2 — Reinforcement and the helix wire
This is the largest cost lever on a suction hose, and the one buyers understand least. In ascending cost:
- Single textile ply + light helix — clean water, short runs, light suction. Cheap and short-lived in sand.
- 2–3 textile plies + helix wire — the workhorse sand suction build at 6″–10″. Most suction hose sold into river sand work is this.
- 4–6 plies, or steel wire braid/helix — high-head suction, long vertical lifts, coarse gravel. Roughly 40–70% more than the 2–3 ply build at the same diameter.
- Ceramic or UHMWPE lined bore — sharp aggregate, slag, high-silica tailings. Two to three times a plain rubber bore, and worth it only when abrasion is the actual failure mode.
If a supplier cannot tell you the ply count and the helix wire diameter in millimetres, you are not talking to someone who makes the hose. That single question separates a fabricator from a trader.
Variable 3 — Rubber compound
Natural rubber (NR) is the default bore for sand and gravel: best abrasion resistance, moderate cost, poor oil resistance. SBR is cheaper and a little less abrasion-resistant — common in budget builds, and one reason a cheap quote is cheap. NBR is for oil-contaminated slurry; EPDM is for heat and ozone, not abrasion.
The per-metre cost gap between NR and SBR at the bore is modest — often 5–12%. The service-life gap on silica sand is not modest. Ask which compound is in the bore, and ask for the abrasion loss in mm³ per ISO 4649. We publish our own abrasion test method and results for exactly this reason — a supplier who quotes the number is a supplier who tests.
Variable 4 — Working pressure and vacuum rating
Suction hose is usually quoted at 1.0 MPa (10 bar) working with a 3:1 or 4:1 burst ratio. Most sand suction lines only need 1.0 MPa; the vacuum rating matters more than the pressure rating. Booster-pump suction and long vertical lifts are where 1.6–2.5 MPa earns its money. Moving from 1.0 to 2.5 MPa at the same diameter typically adds 25–45%, because both the reinforcement and the flange change. Do not buy 2.5 MPa “for safety” on a standard suction run — you pay for reinforcement that does nothing and add weight that makes handling worse. If your line pressure is not something you can state from memory, start with what 1.0 MPa and 2.5 MPa mean on site.
Variable 5 — End connections
On a suction assembly the fittings are often more than half the delivered cost. A pair of carbon steel flat flanges on a 10″ hose adds roughly $40–70 per assembly; SS304 roughly doubles that; SS316 doubles it again. Swivel flanges — worth every cent on a floating line because they save a full rotation at install — add a further premium.
This is also where cheap quotes hide. “With flanges” and nothing else means carbon steel, drilled to whatever standard the factory had on the shelf, no gasket, no bolt set. On a saltwater suction line that is a two-year corrosion problem you bought at a discount. Camlock and pin-lug couplings are the other common option on the suction side for short, frequent-change connections — cheaper than flanges, faster to swap, and what the Peru order below used.

Variable 6 — Length and order quantity
Suction hose is made in standard lengths — commonly 6 m, 11.8 m, or 12 m — because that is what fits a 40-foot container without an out-of-gauge freight bill. Custom lengths add setup cost. We covered the shipping side in how oversize diameters load into a container, and it is worth reading before you specify a 13 m length.
Quantity matters less than buyers assume: a 300 m order and a 1,000 m order from the same factory usually differ by only 8–15% per metre, not 40%, because the vulcanising cycle — not the raw rubber — is the constraint. If a supplier drops 40% when you double the quantity, ask what changed in the build.
Variable 7 — Flotation (or not)
A suction line on a floating dredge needs buoyancy. You can either build a self-floating hose (foam core, closed-cell, integral) or hang a plain hose from external floaters. Self-floating suction hose costs 40–60% more than the plain equivalent at the same bore, but it removes the separate floater system and the failure points that come with it. Our floating hose range shows the build. For a fixed, shallow intake you do not need flotation at all — and paying for it is waste.
A note on “per metre” pricing: some listings quote per metre but ship per piece, per roll, or per 6 m length. Always confirm the unit before comparing — we have watched a $2.10/m quote become $12.60/m at the proforma stage, same supplier, same page.
2026 price bands by diameter (suction hose, FOB China)
These are realistic FOB China bands for a standard sand suction rubber hose — 2–3 ply textile with helix wire, NR or SBR bore, carbon steel flange or camlock, 1.0 MPa — the build most river sand operators actually buy. Add 25–45% for SS316 ends and 40–60% for self-floating construction.
| 4″ / DN100 | $9 – $16 / m |
| 6″ / DN150 | $14 – $24 / m |
| 8″ / DN200 | $19 – $32 / m |
| 10″ / DN250 | $25 – $42 / m |
| 12″ / DN300 | $36 – $58 / m |
| 14″ / DN350 | $48 – $75 / m |
| 16″ / DN400 | $62 – $95 / m |
The budget end of each band is the short-length, camlock, SBR version — exactly the Peru order below. The top of each band is a 4-ply NR build with stainless ends. Quotations below the band for a given size are almost always missing reinforcement, helix wire, or the flanges. Quotations above it should arrive with a test report, a named compound, and a flange drawing.
A real order, start to finish: 200 metres at $15 per metre
Price bands are easy to write and hard to trust, so here is one actual suction hose order with the numbers left in.
A river sand operator in Peru had been buying 10-inch suction hose from an incumbent supplier. Two things pushed him to look elsewhere: quotations that came back vague and untechnical, and delivery dates that kept slipping. He found us through Google, wrote in Spanish, and got an answer the same evening — in Spanish. That last part mattered more than it sounds; he had already dealt with suppliers who took two days to reply and then answered a different question.

The duty. Fresh water, a stony river bed, dredging from about 12 metres down and pushing the slurry roughly 400 metres to shore at around 20% solids — running 12 hours a day, twelve months a year. Stone matters more than sand in this application: a 10-inch suction hose on a stony bed takes impact as well as abrasion, and at that depth the suction side runs a hard vacuum — exactly the collapse condition the helix wire exists for. That is a harder duty than the same bore on clean sand.
What he was actually afraid of. Not the price. He had three concerns: that a cheaper bore would wear out faster than what he was running, that the delivery date would slip again and stall his season, and that a supplier he had never used could not hold a dimensional tolerance on a short length. That last one is not paranoia — a 1-metre cut of 10-inch hose has very little room for error.
What he ordered.
| Diameter | 10 inch (DN250) |
| Length | 1 m per piece × 200 pieces (200 m total) |
| Bore compound | SBR |
| Working pressure | 1.0 MPa |
| Ends | Camlock |
| Packing | Wooden crates |
| Total order value | USD 3,000 — about $15 per metre, FOB China |
| Lead time | 20 days from deposit |
Note what that $15 buys: a 1.0 MPa working rating, an SBR bore, camlock ends instead of flanges, and a short cut length with no assembly labour. It is a real suction hose for a real job — it is simply not the same product as a 4-ply natural rubber hose with SS316 flanges at $42. This is the whole point of the seven variables above. The $15 quote is not a lie. It is a specification.
The problem that showed up. Some of the 1-metre lengths came out 5 mm over. Rubber moves with temperature — a 1 m cut has no slack to absorb it, and our tolerance on that run was looser than it should have been. We caught it before the crates closed, told him rather than shipping quietly, and sent photographs and video of every crate before it left the factory. He measured the 5 mm against his couplings and decided it would seat without leaking. No replacement, no claim, no delay.

We include this because a case study with nothing wrong in it is not a case study. The 5 mm was our error. What he was buying, in the end, was not just hose — it was being told about the 5 mm before the container sailed.
Where it landed. Eight months in, roughly 200,000 m³ moved, no suction hose replaced. His previous supply had needed changing at about the four-month mark in the same duty — same river, same pump, same crew. By his own estimate, the avoided downtime is worth roughly USD 50,000 over the period. That figure sounds inflated until you price a stopped dredge: one unplanned hose change here costs a full working day with the crew standing idle, and a working day on this river is measured in thousands of cubic metres that did not move. He has stayed with us since.
What this order teaches about price: he did not switch to us because we were the cheapest quote. We were not. He switched because the previous supplier could not answer a technical question and could not hit a date. On a 200 m order worth $3,000, roughly doubling service life is worth many times the gap between the lowest and the highest quotation he received.
The number that actually matters: cost per cubic metre moved
Comparing suction hose on purchase price alone is how operators end up buying three hoses a year. What you want is cost per cubic metre of material moved, and that has four inputs:
- Purchase price of the hose and its end fittings
- Service life in operating hours before the bore is worn through or the helix fails
- Downtime cost per replacement — a mid-river suction hose change on a working dredge is rarely under four hours, and on a large cutter suction dredger it can cost a full shift
- Replacement lead time — a hose that arrives in 45 days forces you to hold spares you would not otherwise need
A hose at $28/m that lasts 3,000 hours beats a hose at $16/m that lasts 1,200 hours by a wide margin, before you count the two extra change-outs. This is why serious dredging contractors buy on specification and test report rather than on the lowest line in the comparison sheet. For the discharge side of the same line, the full dredge hose cost-per-metre breakdown works the numbers the same way.
How to read a suction hose quotation: 10 points that must be on it
If any of these is missing, the quote is not comparable to another quote — it is just a number.
- Inner diameter in mm (not just inches)
- Overall length in metres, and whether that includes fittings
- Wall thickness in mm
- Bore compound (NR / SBR / NBR / lined) and hardness in Shore A
- Helix wire diameter and ply count — the collapse-resistance spec, unique to suction
- Cover compound, and whether it is UV/ozone stabilised
- Working pressure and vacuum rating, plus burst pressure
- Safety factor
- Flange material, drilling standard, and whether bolts and gaskets are included (or coupling type)
- Incoterm, port of loading, lead time, and packaging
Two quotations that both answer all ten can be compared. Two that answer four cannot, and the cheaper one is almost always the one answering fewer — usually the one that forgot the helix wire.
Suction vs discharge: why the suction side is often cheaper
For the same diameter and bore compound, a suction hose is frequently priced a little below its discharge twin, because the suction side is commonly run at 1.0 MPa while the discharge side on a booster line runs at 1.6–2.5 MPa. Less pressure rating means less reinforcement and a lighter flange — and a lower price. The trade is that the suction hose carries the helix and the vacuum duty instead, so you are not “getting less hose,” you are getting a different hose. The SRH-vs-DRH explainer works through which end of your line needs which rating.
Where HDPE wins on price, and where it does not
For long, straight, permanent suction runs, HDPE pipe is usually cheaper per metre than rubber at the same bore — often 30–50% cheaper at 8″ and above — with lower friction loss and a longer life on benign slurry. It loses on three things: it does not flex, so you need bends, anchors, and a shoreline that suits it; it cannot be coiled for relocation; and it does not tolerate the same abrasion severity as a thick natural rubber bore on sharp sand and gravel. Floating HDPE lines also need a separate buoyancy system. Rule of thumb we use: straight, fixed, long run on fine sand — HDPE. Moving dredge position, sharp aggregate, or the short flexible connections at the pump and the intake — rubber. Most real installations need both, joined at a transition piece. If you are not sure which side of that line your job falls on, the rubber-vs-HDPE comparison works it through case by case.
Frequently asked questions
How much does a 10-inch sand suction hose cost in 2026?
Expect $25–$42 per metre FOB China for a 4-ply natural rubber suction hose at 1.0 MPa with carbon steel flanges or camlock. The budget end — short lengths, SBR bore, camlock — can land near $15/m, as the Peru order above shows. Quotations below $12/m for a 10″ suction hose are usually missing the helix wire or the plies.
Why is one supplier’s price half of another’s for the same size?
Almost always one of three things: fewer reinforcement plies, a thinner or absent helix wire, or flanges not included. Ask for the ten-point quotation above and the gap explains itself within one email.
Does a higher price mean longer life?
Up to a point. Going from a 2-ply to a 4-ply build measurably extends life on abrasive duty. Going from 4-ply to 6-ply on fine sand often does not, because the failure mode is bore wear, not structural collapse — you would be buying reinforcement that never gets loaded. Match the build to the failure mode you actually experience.
What is the minimum order quantity?
For standard sizes, usually one container load — but how many metres fill a container depends heavily on diameter, and the biggest bores are ordered by the piece. Below a full load, per-metre pricing rises because the setup cost spreads over fewer metres. Small trial orders are possible and we do them, but expect to pay a sample-level rate. Note also that quantity only moves the price 8–15%; the build moves it far more.
How long is delivery?
Standard specifications: 20–30 days ex-works, plus 25–35 days sea freight to most destinations. Custom flanges, non-standard lengths, or self-floating builds add 10–15 days. Plan spares around the 60-day figure, not the 30-day figure.
Can I get camlock instead of flanges on a suction hose?
Yes. Camlock and pin-lug couplings are common on the suction side for short, frequent-change connections — cheaper than flanges and faster to swap. They are what the Peru order used. For high-pressure booster suction, flanges are the safer choice.
