Tanker loading and vapour recovery hose: reeling hose, composite and dry disconnects

A fuel tanker uses three different hoses and a coupling that must not drip. What a reeling hose is built for, why vapour recovery is composite, and when a dry disconnect earns its price.

Tanker loading uses reeling hose, composite hose and dry-disconnect couplings.

At a glance

Key takeaways

  1. Reeling hose must coil on a drum day after day; A420 is a 17 bar, DN35 / 1-1/2" hose with textile yarn and two copper anti-static braids.
  2. Vapour recovery returns displaced fuel vapour to the tank; our A901AG is composite to EN 13765:2015 Type 3, 14 bar, DN75 and DN100.
  3. Composite oil hose (A901GG) is 20 bar from 1" to DN100, lighter than rubber of the same bore.
  4. Dry disconnect couplings close a valve in each half before the halves separate, so the joint parts without a drip.
  5. Our Sealfast dry disconnects pair only with Sealfast halves of the same size; they are rated up to 150 psi.

A road tanker is a hose application in miniature: a reel that coils a delivery hose dozens of times a day, a loading connection that has to seal against fuel, and a vapour line that keeps the displaced vapour out of the air. Each one wants a different hose, and the connection between them wants a coupling that does not leave fuel on the ground when it is broken.

/01The reeling hose.

A delivery reel winds the hose on and off a drum at every drop, so the hose has to be flexible, light enough to pull, and tough on the cover. Our A420 tanker reeling hose is rated 17 bar with a 51 bar minimum burst (SF 3:1), in DN35 and 1-1/2". Its tube is smooth NBR listed for diesel, domestic fuels and unleaded petrol; it is reinforced with two high-strength textile yarns and carries two copper braided anti-static wires; the red cover resists oil, abrasion, ozone and weather. It is rated −20 to +70 °C.

/02Composite for loading and vapour.

Composite hose is built from layers of polymer film and fabric between an inner and an outer wire, with no bonded rubber at all. It is lighter than rubber of the same bore and its film layers can be chosen for the product. Our vapour recovery composite hose (A901AG) is printed EN 13765:2015 Type 3, rated 14 bar with a 4:1 safety factor, −30 to +80 °C, in DN75 and DN100, with an orange PVC cover and a galvanised external wire. Our oil composite hose (A901GG) is rated 20 bar from 1" to DN100 for fuel and oil transfer.

Composite hose needs composite fittings: a spiral tail that threads into the hose's internal wire, held by a ferrule or lug nut. Our composite fittings — cam lock C and E with spiral tails, female liners with lug nuts, hex male and flanged tails — are made for composite hose; Sunpool publishes no working pressure for the fittings themselves.

/03Dry disconnect couplings.

A dry disconnect coupling has a valve in each half. Connect them and both valves open; disconnect and both close before the faces part, so the joint breaks with no spill. Our Sealfast dry disconnect couplers and adapters are aluminium with 316 stainless valve parts, 1-1/2" to 3", on a female NPT back, with Viton or PTFE-encapsulated seals — PTFE where the product is an aggressive acid or solvent. They are rated up to 150 psi, and the Viton coupler is listed to 28" Hg vacuum. They use a proprietary face: pair only with Sealfast halves of the same size.

For heavier tanker duty, the metallic shelf adds Met-O-Seal tanker couplings (MTS4 heavy duty, 2" to 6", 25 bar; MT3TL lightweight, 2" to 4", 16 bar) and the T92H dry-break quick coupling, 1" to 6" at 70 bar with an API 6FA fire-test option.

Frequently asked questions

What is a tanker reeling hose?
A flexible fuel delivery hose built to be wound on and off a reel. Our A420 is 17 bar, 1-1/2", with an NBR tube for diesel and unleaded petrol and two copper anti-static braids.
Which standard covers vapour recovery composite hose?
Our A901AG vapour recovery hose is printed EN 13765:2015 Type 3, the European standard for composite hose, rated 14 bar.
Are dry disconnect couplings interchangeable between makers?
Not necessarily. Our Sealfast dry disconnects use a proprietary face and pair only with Sealfast halves of the same size.
Do composite hoses need special fittings?
Yes. Composite hose uses spiral-tail fittings that engage its internal wire, held by a ferrule or lug nut. Sunpool designs ours for composite hose, and the spiral tail suits most composite hose worldwide.

    Where we supply this hose

    For chemical, food-grade, steam and water hose the certificate is most of what the buyer is actually purchasing, so it is prepared before dispatch rather than chased afterwards. We ship this class of hose from Dubai into plants audited against the same standards we quote to, with the documentation attached to the consignment and referenced on the invoice.

    GCC & Middle East

    Western & Northern Europe
