Product Questions & Answers

got a pressure washer hose with a 1/2-14 female NPT end, is this the right quick coupler half to screw onto it?
Question by: Norm M on Mar 2, 2026, 4:49 PM
For a 1/2-14 female NPT connection, the threaded side on this coupler matches that size and thread. It is the male half quick coupler with a 1/2 inch coupling size.

Will this fit my pressure washer if it's got a 1/2-inch female NPT fitting?
Question by: Phil A on May 24, 2025, 11:58 AM
Yes sir, this coupler's got a 1/2-14 female NPT thread, so it should screw right on if your pressure washer has the standard 1/2-inch male NPT.

Got a pressure washer running 3800 PSI and need to swap out a busted quick coupler, this a male half with female NPT threading on it?
Question by: Ricky H on Jul 22, 2025, 7:49 PM
Correct on both counts. The coupling is the male half of the quick connect setup, and it threads into a 1/2-14 female NPT port. At 3800 PSI you'd have solid headroom under the 4000 PSI rating, so it should hold up fine for that application.
