Anyone have any idea what the rated pressure limit of a compression type joint is on a copper pipe system?

I am looking at running around 150-200PSI diesel in a 1/4" copper pipe.... I do NOT want it to let go!

I'd worry more about the pipe than the fitting- copper pipe is pretty soft!

Brakes will see in excess of 1000psi with copper compression fittings.

200psi is nothing at all really. An air compressor will get near that!

Had totally forgotten about brake systems! Looks like I should be ok

Back when I owned a London Taxi you could buy compression fittings to repair the ends of broken injector lines - well over 200psi

The interweb says 912 psi for 1/4-inch pipe - so that leaves the fitting......


Olive type fittings are found on all sorts of high pressure pipes - I would think you will be fine

Might be pushing your luck at 200psi

Bang on, thanks for the details! I was looking earlier and my google skills failed me!

Looks like that is one less thing to have to worry about..
