Review on Robinair 69072A Enviro Guard Quick Fittings by Lamar Hopkins

We purchased these fittings for our automotive repair shop and they have caused more problems than they solved. Based on our own experience, we cannot recommend these fittings. The only positive aspect is that they were easy to install .However, we had ongoing issues with leaks and poor connections which caused us to go back and manually tighten them multiple times. We ended up having to replace them with higher quality fittings, which were more expensive but worth it in the long run..
