Orion Motor Tech AC Gauges, AC Manifold Gauge Set for R134a R12 R22 R502, 3 Way Automotive AC Gauge Set with Antishock Gauges Hoses Couplers Adapter, Puncturing Can Tap Freon Recharge Kit

I cant attest to long term durability but it worked great when I used it. Seems pretty quality for the price.

These are nice gauges. Easy to use with fairly clear instructions. Not that all backyard mechanics should be tinkering with auto AC but if your a bit more advanced like myself and study up a bit, these can help check your AC system. I still recommend professional service for the AC system as people have been severely hurt accidentally tapping into the high pressure line blowing up those small cans. I only use it to check the system pressures to jint what might be an issue.

I never used a gauge set like this before buying this. I’ll say it seems to work well. Everything went together good with no leaks or problems. Comes in a nice case to store it all when not in use. My only complaint is it comes with the piercing can tap. All the cans of refrigerant you buy in the store are self sealing so you have to buy it separately. Had I not read others reviews of this set and other brands I would not have known this. The tap isn’t expensive it’s just the point. Overall I’m happy with the set. I’ve used it on 4 cars so far and it’s did what it needs to each time. For the price you can’t go wrong.

I needed a set of gauges to replace a set that were borrowed and never returned (shame on me). I am a 40+ year heavy truck technician (retired) so I didn't want to spend a ton of money on a new set of professional Master Cool gauges at my age. I saw this set for a very good price and decent reviews so I took a chance. I used them today and they worked very well for what I needed then for. There were two minor things that I had happen to me during my first use worth mentioning. The first was that the hoses loosen up way too easily on the quick connect fittings every time you move the gauge set around. I had it blow some refrigerant out of the system before I could get to the fitting to tighten it (and frost burned my hand reaching in there). The other thing is the can tap is terrible. It took me 3X as long as it should have to put one 12oz can in the system the way it trickles through the tap. If you buy this set, just buy a better can tap. No big deal. I still recommend these for occasional use once in a while. They just are not for made for everyday use as a professional technician.

I've used these for a long while now and they are great. Have had no issue and only productivity. Great gauges.

Well for starters, the performance is good the sound quality is very low to where it doesn't make a bunch of noise it is pretty durable I'd say. The quality is good because the size is compact it's got a little weight to it but you know it's not going to break because it's not plastic it's metal. Now the one thing I really do like about it is the pressurizing by using it to evacuate any fumes or any little bits of liquid out of any pressurized container is pretty good and it makes sure that it holds its place for pressure the connectivity is easy to assemble easy to follow but one thing that it does not do so well is replenish the refrigerant in your AC line as well you have to buy a separate can pump that actually has a gauge on it to put more refrigerant in your AC line but this helps pressurize it to where when you do put the 134a or whatever refrigerant you have in your vehicle it creates such a vacuum packed that any liquid that hits that chamber immediately gets dispensed into the capacitor which means you're not going to get a bunch of air in there unless you put the air in they're yourself. Overall it was a complete success. Both my vehicles have AC and I did not have to pay $1,000 mechanic bill to get my AC refilled.

Connected this to the AC service ports in my 2013 Kia Optima that uses R134a refrigerant to check the pressures, which has a notorious problem with its thermal expansion valve. This product performed very well and read accurate pressures that correspond with the hot air from the AC system. I also need to point out that I attempted to use this on a 2020 model vehicle with a good working AC for comparison purposes but did not realize it uses the more modern r1234yf AC system, thus my valve connectors did not fit. I still plan to have the system evacuated, then I will vacuum and refill the refrigerant after replacing the faulty expansion valve. I look forward to updating this review afterward. UPDATE The recharge process went well and these gauges were excellent. Definitely a great purchase for the DIY person who needs something inexpensive for a few uses. No leaks at all.

My expectations weren’t high from the start given the price point but I didn’t anticipate catastrophic failure on the first use — which ultimately created a dangerous situation. While recharging an automotive A/C system with R-134a, refrigerant unexpectedly began spraying out from hair line cracks in the manifold section on both the high and low sides once the pressure reached ~225psi. These gauges should hold well over 225psi safely without concern of the manifold body failing and releasing gas/liquid refrigerant all over the user. I guess you get what you pay for.
