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.
