Refrigerator Freon Recharge Kit, R134A AC Refrigerant Charge Hose Set with Pressure Gauge,1/2" Acme, A/C Recharge Measuring U-Hose Can Tap, Perfect for Car AC Air Conditioning Refrigerant

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.

Great to have this item for adding Freon . Great purchase

Product does not work. It failed miserably to connect to the low pressure side of the valve. It just sits there. If pressed on, it will instead release the pressure and Freon will escape instead.

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.

GOOD QUAILITY, THE HOSE IS TOO SHORT. IF YOUR A.C. PORT IS ON FIRE WALL IT'S DIFFICULT TO HOOK CAN UP WITH ALL THE OTHER STUFF IN THE WAY.

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.

Make sure you're fittings fit correctly

I had purchased a bunch of small freon cans and needed a system to administer. This was priced very reasonable, and it worked fantastic. I liked the added gauge feature.
