Question by: Vince W on Apr 24, 2025, 5:10 PM
Hey, reckon this'll hook up to my pressure washer alright? Got a 3/4 inch NPTF fitting on it.
Answer by: Customer Support on Apr 26, 2025, 6:43 AM
It'll fit right up. The female end of this coupling is a 3/4" NPTF, so it should be compatible with your pressure washer as long as it has a matching male connection.
