Overview

The 1/4M Plug 1/4F NPT is the plug half of a 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 1/4 inch male quick connect profile on the outside and a 1/4 inch NPT female thread on the inside, so it slides into the matching coupler and screws onto a 1/4 inch male port.

Because the plug is the accessory side of a quick connect, it mounts on the item that gets changed between jobs, such as a lance, a nozzle or a wash down tool. The operator keeps the coupler on the machine and swaps the accessory by changing the plug. The stainless steel body keeps the fitting free of corrosion in constant wet use.

Frequently Asked Questions

What is the difference between a plug and a coupler?

The plug is the half that slides into the coupler and locks, and it carries the thread that screws onto the accessory. The coupler is the half with the release collar that stays on the machine or hose side. Together they make a tool free quick connect joint.

What pressure is the plug rated to?

The listing states 5000 psi. That puts it at the top of the pressure washer range and makes it a match for the high output machines, as well as most commercial pressure cleaners. The rating covers the diesel and hot water machines in the pressure cleaner range, where the fittings see sustained high output work.

What thread is on the plug?

The plug carries a 1/4 inch NPT female thread, so it screws onto a 1/4 inch male port. The quick connect profile on the outside is the 1/4 inch size that slides into the matching coupler.
