R134A Car Air Conditioning Refrigerant Charging Hose kit with Pressure Gauge,1/2 Acme, AC Recharge Measuring U-Hose Can Tap, Perfect for Automobile and Home A/C Freon Charge U-Hose

Received it and well packed. Works great and my car AC worked again. It was low on freon according to the gauge meter and refilled with R-134a to the recommended Low pressure.

I had no problems from the get go. Cheap and accurate way to recharge my automobile AC unit. First it might help to read up on how to administer refrigerant or watch a few you-tube videos. Make sure you are attaching to the "low" pressure or suction side. The valves in newer autos are marked "L" for low and "H" for high. The snap on end takes a little previous practice (?) . I've used this type in air compressor lines. The refrigerant cans are usually self sealing so when you turn the piercing valve all the way down it should open the can valve or back off slightly. You can feel the can getting cold if gas is being suctioned. I usually put the can in warm water at last to speed up the emptying of can. Whether this is safe(?). I've done this many times and no problems. So, for the money: this charging unit is a good investment.

This has a cheaply made plastic cover which pops off when trying to put freon in, the gage stops working because of heat engine. Overall its seems to be a strong tool with the exception of the round plastic cover over the gage needs to be made where it does not pop off. It is useless without the gage cover because of engine heat it reads inaccuratle

Gauge was accurate and was easy to recharge my cars air-conditioner. The ends a good quality and fit the nipple as designed. Very happy I found this quality product.

I would have paid another 50 cents for a longer hose.
