Mi T M Corp AW-0023-0490 Screw Coupler 3/8 Inch Fnpt X M22

Product Description

The MI T M CORP AW-0023-0490 is a pressure washer screw coupler designed to connect a 3/8 inch Female National Pipe Thread (FNPT) fitting to an M22 threaded connection. This fitting serves as an adapter between the pump outlet or wand assembly and the high-pressure hose or spray gun. It is a small but critical component in maintaining a leak-free, high-pressure water circuit. Plumbers, equipment technicians, and pressure washer service professionals install this part during routine maintenance or when replacing worn or stripped couplers. The unit weighs 1 pound and is packaged in quantities of 4.

This coupler is suited for use on residential and light commercial pressure washers that use the M22 connection standard paired with 3/8 inch FNPT plumbing threads. It is a practical stock item for service shops that maintain multiple pressure washer units, and it is also applicable for field repair situations where a damaged or cross-threaded coupler needs quick replacement. The FNPT thread type follows standard pipe thread specifications, making it compatible with a range of compatible fittings in the high-pressure water circuit.

Installation Notes

Installation should be performed by a qualified technician or experienced service professional. Always relieve all pressure from the system and shut off the water supply before removing or installing any pressure washer fittings. Use appropriate thread sealant or PTFE tape on FNPT threads per manufacturer guidelines to ensure a leak-free connection. Do not overtighten the M22 connection, as this can damage the threaded seats on the coupler or the mating component.
