Calin Brabandt from Peck, ID United States
Good quality fitting for the price but beware the o-ring, which appears to be EPDM. (There are better o-ring compound choices for this application!) My o-ring dissolved in less than an hour, because I use SuperLube Multi-Purpose with PTFE lube in all my HPA systems to reduce friction and corrosion. My male fitting must've had only a trace of lube on it but it still killed this quick disconnect o-ring in no time! Use only pure silicone o-ring lube with EPDM, e.g., SuperLube "O-Ring Lube." I replaced the o-ring with a 010 size 90 durometer Disogrin urethane o-ring and was back up and running in no time. The fact that the new 90 duro o-ring seals well is testimony to this fitting's excellent dimensional tolerances, which a duro 90 urethan o-ring requires to perform well in this application. Not all low-priced fittings seal this well!
