LIYYOO R134a AC Refrigerant Recharge Hose Kit, with Measuring Pressure Gauge and 1/2’’ Acme Can Opener Tap Dispensing Valve Fit for Car AC Air Conditioning Refrigerant Charging

This works well with the new self sealing Freon cans. The gauge is helpful and already saved my brother over $200. He had added Freon in his car with a hose that didn’t have a gauge. As a result, he overfilled the system and the system in his car wasn’t cooling.He was about to have it professionally serviced for $200 when I connected this and discovered that it was overcharged.It was a quick fix with this hose and gauge to get the right pressure in the system.

Excellent did job very well, arrived next day. Best price in the World. I Love in A Cold World now. Thank You

As advertised. No instructions

Very simple to use and gauge is accurate.

I bought a car that the ac didn’t work. Got lucky, used this to install one can of R134 and now have cold ac.

You can charge Freon with this setup, but the cable is very short for reaching an AC port and positioning the Freon can in a crowded engine bay. Twice the length would have been much better. All the connections are crimped, so no adjustment is possible. Also, this is a puncture-type can tap, and won't work with the newer self-sealing cans. That should have been specified in the listing.

keep the ac running the way it should

At time of purchase, product does not state that it will not work with self-seal refrigerant cans. Only piercing cans
