Question by: Neil W on Oct 7, 2025, 1:43 PM

replacement part question - got a 1/2 inch female NPT fitting on my pressure washer wand setup, will this coupler thread right onto it without needing any adapters?

Answer by: Customer Support on Oct 9, 2025, 9:02 AM

A 1/2-14 female NPT thread is exactly what this coupler carries, so if your wand or hose end is also 1/2-14 NPT male, it threads on direct with no adapter in between. The coupling size is 1/2 inch, which lines up with a wide range of standard pressure washer accessories built to that same sizing. Just make sure your existing fitting is NPT and not a different thread standard like BSP, and you should be good to go.
