Air Induction Check Valve Fitting

Hi all,
Anyone know the size of this fitting or a part number? I am also looking for the correct size flare tool.

It appears to be an M22 fitting with inside diameter of 14mm.

An M22 oil drain plug was useful for plugging the hole in my headers, after I managed to unscrew the factory piece. The dual-cat manifolds (96/97) have a smaller diameter.

I'm looking for that actual fitting. I can dress these threads up and re-use if I have to, but was gonna clean it up and reinstall it when I put my manifolds back in.
