R134a Refrigerant Recharge Hose Kit for Refrigerator A/C System, R134a/R-12/R-22 Freon Can Tap Recharging Hose with Detachable R134a Quick Coupler - Easy to use

It works for car ac recharge, works for r134a cans. It would be more helpful if a brief instruction is included.

This worked like a champ with the self-sealing R134a cans I got at W@lmart. I was a little leery after reading some of the negative reviews, but was desperate to find something that had less negative reviews than this did and couldn't find anything better at this price point. The only slight negative issue I had, was when I connected an R134a can to the self-sealing adapter/valve/hose/gauge assembly, there was momentary leakage (liquid spray & gas) until the can was fully screwed onto the adapter. I strongly suggest wearing safety goggles/gloves and having a pair of pliers or wrench handy for this reason. I've recharged my cars refrigerant many times in the past, but always with the old piercing type cans. This was the first time with the self-sealing cans. For all I know, momentary leakage is normal when connecting anything to self sealing cans. Everything else worked perfectly with this hose/gauge/valve device. Overall, 4.5 stars (deducted a half star for the leakage)

I only used it once and it worked great. Saved me a lot of money. Not having to pay your mechanic.

This particular AC hose/gauge was the only one I could find that wasn’t a “frequently returned item.” It seems to have worked fine, but I’ve only used it once so far. We’ll see.

Item worked great. Used it to add freon to car AC. Doing so made the AC cold again.
