Does anyone know what size the threads are on this bottle warmer pressure switch? I need an inline adapter and need to know the thread size. Also where can I get an inline adapter for this with a 4an line. This is a cold fusion switch. Thanks, Josh

 

The Switch should be 1/8th NPT ( National Pipe thread ).

This is a -4 manifold with a 1/8th NPT port on it.

I would have thought so too, but it is bigger. I tried to stick it in the gauge port on the side of my bottle and its too big. I need an adapter this size but cant seem to find one. Thanks for the help though, yalls customer service is second to none, Josh

 

Is it 1/4in?

That's 1/4" NPT. Unfortunately your only option is going to be to drill out an 1/8" NPT fitting and tap it for the 1/4"NPT. Or try giving cold fusion a call.

I think its a 1/2 "

 

Looks way too small for 1/2" NPT. I'm definitely leaning towards 1/4" based on the pic.

 

Here is the NPT size>outer diameter>threads per inch
1/16" 0.3125" 27
1/8 " 0.405" 27
1/4 " 0.540" 18
3/8 " 0.675" 18
1/2 " 0.840" 14
3/4 " 1.050" 14
1 " 1.315" 11½

If it measures about 1/2" is is most likely 1/4NPT.

 

It measures right around 1/2" so it must be 1/4 npt. Thanks guys I will look around for a fitting, Josh
