Overview

The 3/8M Plug 3/8F NPT is the plug half of a 3/8 inch stainless steel quick connect fitting for pressure washers. The listing describes it as a quick connect NPT thread fitting rated for 5000 psi and made from stainless steel. It carries a 3/8 inch male quick connect profile and a 3/8 inch NPT female thread, so it slides into the matching 3/8 inch coupler and screws onto a 3/8 inch male port.

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. The plug mounts on the accessory side of the line, so the operator changes lances and tools by swapping the plug while the coupler stays on the machine. Stainless steel keeps the fitting free of corrosion in wet use. When the delivery line runs the 3/8 inch size, this plug keeps the whole joint in the one thread standard instead of mixing a 1/4 inch fitting into a 3/8 inch line.

Frequently Asked Questions

Is this a 3/8 inch fitting?

Yes. It is the 3/8 inch size quick connect plug with a 3/8 inch NPT female thread, the heavier size in the stainless quick connect range used on high output machines and their delivery lines.

What pressure is it rated to?

The listing states 5000 psi. That covers the high output machines in the pressure cleaner range and makes the 3/8 inch plug a match for commercial units running near its maximum. Keep the fitting within its own rating regardless of the machine it is used on.

Does it pair with the 3/8 inch coupling?

Yes. It slides into the 3/8 inch stainless steel coupling in the range, which carries the 3/8 inch NPT female thread on the other side for a complete quick connect joint.
