Variant context
Standard cam & groove couplings (sometimes called quick-disconnect or "camlock") use two cam arms to engage a male adapter into a female coupler with a soft gasket seal. Industry standard since 1949 for fast hose / pipe / tank connections in low-to-medium-pressure transfer applications. Compliant with MIL-A-A-59326 (US) and EN 14420 (Europe).
How to order
Specify (a) the size (1/2", 3/4", 1", 1-1/4", 1-1/2", 2", 3", 4", 6"), (b) the body material from the available options, and (c) the gasket compound (Buna-N is standard; Viton, EPDM, or PTFE on request for chemical compatibility). Indus engineering will confirm the exact Sealfast part number on the RFQ.
Companion products
Pair with the matching cam & groove half (e.g., Type A pairs with Type B / D / DC; Type C pairs with Type E / F / DP), Sealfast hose clamps, and Indus industrial hose for a complete fluid-transfer assembly.

DATA
Technical Data Sheet — Aluminum Type A Female NPT x Male Adapter Cam and Groove Couplings
datasheet · EN
What is a cam & groove coupling?▾
A cam & groove (also called camlock or quick-disconnect) coupling uses two cam arms on a female "coupler" to engage a male "adapter". The cam arms rotate over a groove on the adapter, compressing a soft gasket to form a leak-free seal. Industry standard since 1949 for fast hose-to-hose, hose-to-pipe, and hose-to-tank connections in low-to-medium-pressure liquid and air transfer.
What does the Type letter mean?▾
Type A is the standard cam-and-groove configuration code: Male adapter (cam-grooved) — engages into a female coupler on one end and Female NPT thread — screws onto a male NPT pipe / fitting on the other. The Type letters are an industry-wide convention — Type A through Type F cover the most common combinations of male adapter, female coupler, NPT thread, and barbed shank ends. Types DC and DP are dust caps and dust plugs.
What sizes are available?▾
Seal Fast lists this range in: 1/2", 1/2 x 3/4", 3/4", 1", 1 1/4", 1 1/2", 2", 2 1/2", 3", 4", 5", 6", 8", 10", 12". Contact us to confirm availability of a specific size.
What materials does this coupling come in?▾
Aluminum, Brass, 316 Stainless Steel, 304 Stainless Steel, Plated Iron, Polypropylene, Nyglass (composite). Aluminum is the workhorse for general-service air / water / petroleum. Brass is used for marine, fuel, and food-contact service. 316 SS is required for chemical, pharma, and corrosive marine service. 304 SS for general SS. Plated iron / polypropylene / Nyglass are budget alternatives for non-corrosive low-pressure service.
What is the working pressure?▾
Up to 250 psi (1/2"–2"); 150 psi (3"–4"); 75 psi (5"–6") — derates with size, see datasheet. Cam & groove couplings are NOT designed for high-pressure hydraulic service — these are LOW-to-MEDIUM-pressure transfer fittings (typically up to 250 psi at sub-2" sizes, derating with size). For high-pressure hose-end fittings, see the Indus hose-fitting range.
What gasket should I order?▾
Standard gasket is Buna-N (nitrile) — compatible with petroleum, water, and most general-service fluids. Specify on the RFQ for chemical compatibility: Viton (FKM) for fuels and aggressive solvents; EPDM for ketones and water; PTFE for the most demanding chemical service. Sealfast supplies all gasket options. Buna-N (nitrile) standard. Viton (FKM), EPDM, PTFE, Neoprene available on request for chemical compatibility
Is this product compliant with industry standards?▾
MIL-A-A-59326 (US), EN 14420-7 (Europe), ISO 16028-compatible cam geometry. The cam-and-groove geometry is interchangeable with all major manufacturers (Dixon, OPW, PT Coupling, Banjo) of the same Type letter and size — Sealfast couplings will mate with any standards-compliant cam-and-groove half from the same family.
Lead time?▾
Common sizes (1" to 4") in aluminum, brass, and SS are typically ex-stock from Indus Dubai. Less-common sizes / materials (6", Nyglass, polypropylene) typically ship within 14 working days. Self-Locking and CrimpTEK variants may add 7-10 days for less-common configurations.
