Variant context
Sealfast Self-Locking cam & groove couplings have spring-loaded cam arms that automatically lock when the cam handles are seated. Prevents accidental disengagement under pressure spikes, vibration, or operator error — required for offshore, hazardous-fluid, and pressurised-air service. Backwards-compatible with standard couplings of the same type.
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.
