Hose Couplings
Cam and Groove Couplings Type A
Cam and Groove Couplings Type A is a group of 36 IMPA-coded items (codes 351701–351742) under Hose Couplings in the Hose & Couplings section (IMPA 35). All of them are priced per piece. The names most often specify aluminium (12 of 36), brass (12 of 36) and stainless steel (12 of 36). The list runs through imperial sizes from 1/2" to 8".
Buying guide
A cam and groove (camlock) coupling joins hoses quickly and without tools: when the levers on the female coupler are closed, they pull the male adapter into the socket against a gasket. Type A is the adapter (male end) with a female thread, used to put a camlock connection on a threaded pipe or valve.[1]
On board they are used on fuel, lube oil, water, slop and transfer hoses and portable pumps. The IMPA lines in this group come in aluminium alloy, brass and stainless steel from 1/2 in upwards. Requisitions come from the engine department or the deck for cargo and bunker hoses.
How to specify it
State the type (A — male adapter × female thread), nominal size, material, and thread form (BSP or NPT) — the thread is the commonest cause of a wrong delivery. Mating couplers are Type B, C or D; dust caps (DC) and plugs (DP) close the ends.[1]
Choose the material for the fluid: aluminium, brass, stainless steel and polypropylene are all common. Gaskets are bought separately in this section (Buna-N rubber or PTFE); specify the one compatible with the medium.[1]
Rules and certificates
Cam and groove fittings were standardised by MIL-C-27487 (dimensions, tolerances, materials, closing torque and pressure ratings), replaced in 1998 by A-A-59326. In Europe EN 14420-7 and DIN 2828 apply. Quoting the standard keeps couplings from different makers interchangeable.[1]
Questions buyers ask
- What is the difference between camlock Type A and Type B?
- Type A is a male adapter with a female thread; Type B is a female coupler with a male thread. They mate with each other.
- Are camlock couplings from different makers interchangeable?
- Couplings made to the same standard — A-A-59326 (formerly MIL-C-27487), EN 14420-7 or DIN 2828 — are intended to mate. State the standard on the requisition.
