Orion Motor Tech R1234yf AC Gauge Set, 3 Way AC Gauges W Hoses R1234yf R134a Quick Couplers Self Sealing Can Tap for Freon Charging, AC Gauge Kit for R1234yf R134a R404a, 3 Valve Manifold Gauge Set

Don’t buy that high dollar set of gauges. This one fit the bill . Works very well.

The kit is great for DIY people.However, once the high side is disconnected, there still remains180 or so psi. of refrigerant in the red hose.Ideally, this residual refrigerant would be purged under vacuum back into a tank.But, slowly opening the gauge's high side valve will release the pressure.Open the valve too quickly and someone could be injured, especially ifdirected faceward.Anyways, when a vehicle is in an accident, perhaps refrigerant is released into theatmosphere as well.So, think about the environment, and drive slowly.

Really nice set !!! Needed separate set for R1234yf and within a few minutes of receiving gauge set had couplers and hoses all tight "no tools needed" and hooked up no leaks and had A/C charged and blowing nice and cold no time at all !!! Quality seems to be really nice !!!! Worked like it should price was good shipping was fast !!!!

I had the unfortunate experience of the AC compressor locking up on my 2018 Tacoma with only 60,000km. A slow refrigerant leak leading to loss of compressor (refrigerant carries the oil, no refrigerant, no oil).I already have a manifold set and vacuum pump for R134 stuff, but needed R1234yf for the Toyota. Threw me off for a minute until I realized the can tap is reverse threaded so people don't mix up the different refrigerant's...even though both off the shelf gasses are propane, what ever...if you are not spending over $150 per can of refrigerant, then you are buying propane, and not the authentic stuff.Gauge set worked great, hoses all connected great, no leaks, gets the job done.

Bought this for my husband. He said it’s pretty good quality and works for what he needs it for. Price was reasonable.
