Stainless steel camlock couplings (cam and groove fittings) are manufactured from grade SS304 or SS316 for high corrosion resistance. They generally range in size from 1/2' to 6', handle operating pressures up to 250 PSI depending on size, and conform to A-A-59326D (formerly MIL-C-27487) standards. Standard Types and Configurations • Type A: Male adapter with female NPT/BSP thread. • Type B: Female coupler with male NPT/BSP thread. • Type C: Female coupler with a hose shank (barb) end. • Type D: Female coupler with female NPT/BSP thread. • Type E: Male adapter with a hose shank (barb) end. • Type F: Male adapter with male NPT/BSP thread. • Type DC / DP: Dust cap (DC) and dust plug (DP) for closure. Technical Parameters • Materials: Body and cam arms cast in Stainless Steel 304 or 316. • Gaskets / Seals: Standard Buna-N (Nitrile); optional Viton, EPDM, or PTFE for chemical/food grade usage. • Pins and Rings: Stainless steel handles, pins, and safety retention rings. • Thread Standards: NPT (National Pipe Thread) or BSP (British Standard Pipe). Pressure Ratings by Size • 1/2' size: 150 PSI • 3/4' to 2' sizes: 250 PSI • 2-1/2' size: 225 PSI • 3' size: 200 PSI • 4' to 6' sizes: 100 PSI If you'd like, let me know:The size and type of coupling you need (A, B, C, D, etc.)The fluid or media being transferredI can help you select the right grade (SS304 vs. SS316) and gasket material.
