Overview

The 3/8M Plug 3/8M NPT is the quick connect plug with a 3/8 inch male quick connect profile and a 3/8 inch NPT male thread, made from stainless steel and rated to 5000 psi. It is the version of the 3/8 inch plug that screws into a 3/8 inch NPT female port, rather than the female threaded plug, so it suits the line where the port is already female.

The listing describes it as a quick connect NPT thread fitting rated for 5000 psi, made from stainless steel. The 3/8 inch size is the heavier quick connect in the range, used on high output machines where the larger fitting carries the flow and the pressure. Stainless steel keeps the plug free of corrosion in the constant wet use of a pressure washer line. It is the plug to use where the port on the accessory is already a 3/8 inch NPT female, so the line does not need an adaptor to make the joint.

Frequently Asked Questions

What is the difference between this and the other 3/8 plug?

The other 3/8 inch plug in the range has a 3/8 inch NPT female thread, while this one has a 3/8 inch NPT male thread. This version screws into a 3/8 inch NPT female port, so it suits a line where the port is already female.

What pressure is it rated to?

The listing states 5000 psi, which places the plug at the top of the pressure washer range and makes it a match for high output machines and most commercial pressure cleaners.

What material is it?

Stainless steel. The stainless body resists the corrosion a pressure washer line sees in wet use, so the plug keeps its action smooth and does not seize on the threads.
