oil pressure gauge question

Question for you guys... I have an old multi gauge I am trying to hook up and I got about two turns in on my compression fitting and it stripped off. Is there a specific fitting I need to find for these older gauges?



the fitting I assummed was correct...

 

Need a pic of the inside of the fitting to see if there is a corresponding angled seat. Most aftermarkets are 1/8" NPT, which might explain why you got 2 threads on it and stripped. Mic what's left of the gauge nipple to see if it can be threaded for a 1/8" male NPT and use a "modern" compression setup.

 

great... I'll check... the fitting has a matching tapper to the one on the gauge.

 

Braze a new fitting on the old one. Possible to solder one too.

 

If that gauge is a Bourdon tube type, brazing it will likely ruin it. Lead solder would work best and hope you don't have a leak.

 

If done (with a heat sink in between the bourdon tube and where the fitting is being installed) correctly, brazing is possible. Possible way of brazing is to soak the bourdon tube in cold water, then quickly braze the fitting.

 

Thanks guys, I drilled my fitting and JB Welded it onto fitting on gauge. Hopefully that will work.
