Replacement Air Injection Check Valve Threads?
So I bunged up my check valve threads on one of my headers. Does anyone know the thread? I suspect it is pipe thread. I am planning on getting a section of pipe nipple and having the end welded on for new threads.

Thanks. It's 1/2" npt on my header manifold. Got a black steel female face bushing and had it welded onto the 3/4" air injections manifold tubing. Looks solid.
