Overview
The 1/4F Coupling 1/4F NPT is the socket half of a stainless steel quick connect fitting for pressure washers, made from stainless steel and rated to 5000 psi. The listing describes how the fitting works: slide back the collar on the socket half of the quick connect, insert the coupler plug, and once the plug is firmly seated the safety collar locks in place.
It is the half of the quick connect that stays on the machine or the delivery hose, carrying the 1/4 inch NPT female thread that screws onto a 1/4 inch male port. Quick connection hose fittings let equipment be installed or removed quickly and safely, and the listing notes they are suitable for most mobile high pressure washers and cleaners. The quick connect system is the standard on trade pressure washers because it cuts the time spent changing tools, and a stainless body keeps the collar moving freely in wet use.

Frequently Asked Questions
How does the coupling lock?
The socket half carries a slideback collar. Slide the collar back, insert the plug, and when the plug is fully seated the collar snaps forward and locks it in place. To release, slide the collar back and pull the plug out. The collar holds the plug firmly while the machine runs, so the joint does not work loose under the vibration of the pump.
What is the pressure rating?
The listing states 5000 psi. That places the coupling at the top of the pressure washer range and makes it a match for the high output machines and most commercial pressure cleaners.
What thread is on the coupling?
The coupling carries a 1/4 inch NPT female thread, which screws onto a 1/4 inch male port on the machine or hose side. The quick connect profile on the other side accepts the matching 1/4 inch plug.
