6″ DI (BS1387) GROOVED RIGID COUPLING ST

The 6 inch di (bs1387) grooved rigid coupling st mech is a robust mechanical piping solution engineered for high pressure stability. built from high grade ductile iron, this coupling is specifically optimized for bs1387 steel pipes. the st (standard) rigid design features a precision keyed housing that locks into the pipe grooves, ensuring zero rotation or deflection at the joint.
This coupling is commonly utilized in fire protection systems, industrial water lines, and hvac applications where a rigid, vibration resistant connection is mandatory. it comes pre fitted with a durable epdm gasket to ensure a leak proof seal and is finished in a high visibility red epoxy coating to prevent corrosion in demanding environments.
