Air Coupler M-Style 1/4" NPT Female

This ROK M-Style air coupler (1/4" Female NPT) is built for everyday shop and farm work. Quick-connect air fittings, couplers and plugs let you connect and disconnect air tools in seconds. Match the coupler style (M-style/industrial is the most common in Canada) and thread size across your hoses and tools so everything fits together.

Drain the compressor tank after each use so water doesn't rust it from the inside. Wrap NPT threads with thread seal tape and check joints with soapy water for leaks. A leaking fitting makes the compressor run more and wears it out sooner, so fix leaks when you hear them. Keep a few spare couplers and plugs on hand; they wear with use.

Use thread sealant tape on NPT threads, and release air pressure before connecting or disconnecting fittings. Never point air at yourself or others.
