got a pressure washer hose with 1/4-18 female npt on it, is that what this coupler takes

Question by: Tommy W on Jan 28, 2026, 3:03 PM

Fit comes down to the thread, and this piece is a male quick coupler half with a 1/4-18 female NPT thread on it. If your connection point is 1/4-18 NPT male, this coupler is the matching female NPT side.
