What is the thread size for this valve on the manifolds? I think it's NPT.
Please help if you know, my DD is down and I'm driving the blazer

Air pump header valve thread size????
- Thread starter K85 Octane

ended up putting some 1/2" NPT caps over the header pungs. I think they are correct, either way they don't seem to be leaking.
I used 1/2" NPT pipe plugs on those check valves on my 250 six in my van--I think in reality the threads are either straight pipe threads or some metric tubing thread.but the NPT pipe is close enough to work OK...
I also put 1/4" NPT pipe plugs on my 350 and 400 SB manifolds to block off the flute pipe ports...or I just used bolt cutters to snip the tubes off and brazed or welded the snipped ends up..those too are straight pipe or metric tubing threads but the NPT plugs work OK ..
