Overview
The Nipple A M22 x 3/8 F is an Italian pressure washer fitting that connects an M22 thread on one side to a 3/8 inch BSP female thread on the other. It is the adaptor used where a gun, lance or hose carrying the M22 fitting has to join a line or a port with a 3/8 inch BSP female connection, so the two sides of the pressure washer plumbing come together without a mismatch.
The listing describes it as an Italian fitting, which is the quality marker used across the M22 range: the threads are cut to the European standard and the fittings are the ones that hold up to the repeated make and break of daily cleaning work. The M22 side of the fitting suits the 14 mm pin used across the machines in the range.

For the premium grade version of the M22 nipple, the M22 premium connector is the match, and the Pressure Washers Accessories range holds the rest of the kit.
Frequently Asked Questions
What does M22 x 3/8 F mean?
It means the fitting carries an M22 thread on one side and a 3/8 inch BSP female thread on the other. That makes it the adaptor for joining an M22 line to a 3/8 inch BSP female port, which is the kind of connection a pressure washer needs when the gun, lance and hose use different thread standards.
What is the M22 side for?
The M22 thread is the standard used across the pressure washer range, and the fitting suits the 14 mm pin used on the machines. It connects to the gun, lance or hose that carries the M22 fitting, while the other side gives the 3/8 inch BSP female connection.
Why does the Italian fitting matter?
The listing describes it as an Italian fitting, which is the quality marker across the M22 range. Italian cut threads hold their tolerance through the repeated make and break of daily cleaning work, which is the reason the trade fittings in the range come from that source.
