Leaking oil pressure pipe

[jimbo]

My oil pressure gauge is leaking where the pipe meets the gauge. More precisely, it looks like oil is seeping from the back if the union nut, where the pipe goes in.

 

Is there some sort of failed seal in there, or does it rely on a tight metal to metal mating joint that has got damaged?

 

Your thoughts are welcomed

How about trying some PTFE tape ?

I did wonder that, but haven't been able to find confirmation as to whether it is oil resistant..

Sounds like its cross threaded! its easy to do! at lest it's a cheap part to replace.

Scrap that.....it is.....

 

Eventually found answer on wikipedia, after looking at countless techie sites

 

I'll give it a go.

For future reference PTFE tape does the trick
