I wanted to try out the difference between some pyro gauges BUT I want to reuse the same manifold fitting. I don't want to end up drilling and tapping again. I just want to reuse the same pipe fitting.

Can I use the 1/8" NPT as my standard tap size??

 

1/8 NPT seems to be the standard for pyro tips.

 

Why not just leave the probe you got in there and hook diff guages to it as you go, one by one?

Both my probs are 1/8th npt though if that helps.

 

So, I can hook-up an AUTOMETER gauge? As long as it has the YELLOW & RED connections?

 

Give Autometer a call. Tell em' what probe you have and they should be able to tell you if it'll work with their guage. They're pretty good folks...

 

I dont know what it would do if you hooked up 2 at one time but I thought you ment you where gonna try diff guages, one at a time.
