Which end connects to what?

The 22mm female end threads onto an M22 male fitting — typically a hose end, trigger gun inlet, or pump outlet — and the 3/8" male plug end snaps into a standard 3/8" quick-connect socket.

Will this fit my pressure washer hose?

It fits any fitting with a 22mm (M22) male thread, which is the twist-on connection used on many consumer and light commercial pressure washer hoses and guns. Measure or check your fitting's thread size before ordering — if it isn't 22mm, this adapter won't thread on.

What is the plug made of?

The plug is coated steel. The coating helps resist corrosion in wet, everyday pressure washer use.

Overview

This is a 3/8" quick-connect male plug with a 22mm female threaded end, made from coated steel. It converts a threaded M22 connection — the twist-on fitting common on pressure washer hoses, trigger guns, and pump outlets — to a 3/8" quick-connect plug, so you can snap components together instead of threading them on every time. Screw the 22mm female end onto your existing M22 fitting, and the male plug end snaps into any standard 3/8" quick-connect socket. At 0.25 lbs it's a small, inexpensive fix for mixing M22 and quick-connect components on the same setup. Verify your fitting is 22mm thread before ordering.
