I was pressure testing a repair I made on a faucet and got bubbles. Not from my solder, though. The 1/2MIP to 3/8" compression fitting was leaking at the crimp band AND the taped threads. All fittings are brand new, undamaged and had good clean threads. The ferrule was tightened until there was a visible "waist" on the 3/8 copper tube (new). Am I doing something wrong or:
1 - should I dope up everything with paste as a mater of practice? or
2 - will this be leak-free to water and only leaks thinner air?
First picture shows the setup. 80psi is trapped in supply line and placed underwater.
Second picture is taken underwater and shows the bubbles forming all over this wrench-tight fitting.
