Question by: Tommy W on Jan 28, 2026, 3:03 PM
got a pressure washer hose with 1/4-18 female npt on it, is that what this coupler takes
Answer by: Customer Support on Jan 30, 2026, 1:27 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.
