Bitspower fittings popping
I'm using Bitspower crystal link tube 16mm OD. The fittings are Bitspower G1/4" enhanced multilink fitting for 16mm ridged tubing. Yes I did use a little lube on these fittings and they have two O-Rings. Also what would the proper tightness of the fittings right now I have them pretty tight any tighter I'm going to need to use tools. What would the proper air psi test, I was told 10 psi. Cant get past 7.
