Thread size advice: thermostat housing heater valve port
Posted: Tue Aug 09, 2016 4:05 am
Greetings,
Searched the forum and found an interesting discussion on BSPT, BSPP and NPT. But so far, no definitive statement on the thread type/size on the Twin Cam's thermostat housing heater valve and temp sensor ports.
Background: my federal Plus 2 came to me with an old Ford heater shut-off valve installed. No leaks. But I'm pretty darn sure it's not British Standard Pipe! Looks like this:

I need to replace it and would like to use something similar, but not happy risking an NPT pipe thread into BSP port, if that's what we're talking about here.
Thoughts?
Thanks,
Randy
