Got a thread that I need ID'd.... it's tapered, 10.3 mm at the base and 9.7 mm at the tip and when checked with a thread gauge the gauged marked "27" fits the threads....

Any ideas what that is?

3/8 fpt ?


Looks like I was wrong

1/8" NPT ?

sounds like 1/8 NPT to me

3/8" 18 0.675"
1/2" 14 0.840"
3/4" 14 1.050"

Unified Cycle Gas thread...

1/8 NPT, i'll give that a shot. Thanks and Happy New Year !

Ive come across that thread too on my Zetec. its used for the sensor which switches the fan in.

Any ideas where I could buy a bolt? I want to hollow it out and fit the temp gauge sensor there. The other sensor on the thermostat housing is being used for my Webber Alpha kit.

Thanks

Ian
