Steve,

EDIT: I looked some more into this thread type, and it is a British Standard Pipe Parallel ie straight. (or Tapered if called for.) SO BSPP in what I could find.....probably other acronyms just like for NPT!!!

BUTTTTT, trying to find a tubing nut in BSPP format is proving to be difficult!

I was also trying to find an adapter to go Female BSPP to Male NPTS (straight threads) but no go! Other way around.....no prob. This way supplier could put NPTS nuts on the heater core and use regular shut off valves from US. OR use the adapter and fit to the original heater valve! Which is what I would love to do.

Just like the Italians to use a British water valve on an Italian car sold in the US......(and elsewhere!)

That explains why the danged nut didn't thread onto the valve just quite as nice as it should have for being new parts!!!! I thought I had some aluminum in the threads from previous fitting....and worked on those threads for quite a while with a thread file....cleaning them up!

Hmmmm, don't have 19TPI on my thread gauge either.

Just like Rosanne Rosannadana used to say.....
"It's Always something!"

Thanks for the great info!!!!!
Steve
