22mm plug to 3/8" Male NPT

M22 style fittings may not be fast but are now widely used in the residential market as a safe and secure way to provide a consistent method for attaching and detaching fittings. When purchasing M22 fittings, the black portion is considered the Coupler. The brass exposed threads are considered the Plug (see 24.0024 for reference) and is meant to thread into the black coupler.

Terminology may vary when referencing M22s among suppliers. 

M22 fittings are all 14mm stems unless notated in the item description as 15mm. If the fitting is 15mm, we will make sure you know it!
