OMT 5FT AC Diagnostic Manifold Freon Gauge Set Fits for R134A R12, R22, R502, with Couplers, Adapter for Car A/C System Automotive Air Conditioning Maintenance

I do vehicle repairs for myself, friends, and family. Part of that includes fixing air conditioning systems. I only need to use the gauge manifold a few times a year. Since I'm not actually making money with the repairs, I can't buy more expensive sets. When one breaks, I have to go with what I can afford at the moment. This was one of those purchases. I have 4 sets now, with this one fully working, and the other 3 at various states of brokenness.After finishing the most recent car, I hooked up my old gauges, to pull a vacuum on the system. Both the high and low side gauges were hard against the max pins. {sigh} I blindly pulled a vacuum, and ordered the new gauge manifold set. You can do the job with a gauge that doesn't have the vacuum section, but it is best to be able to see that it's right.The gauges moved fluidly throughout the whole charging cycle. The quick disconnects were easy enough to put on and take off. That's not always easy on the high pressure side, but that's normal.Everything you see in the photos, except for the actual can of r134a and the temperature/pressure reference card, were included with the set.You really should have the temperature/pressure reference card. I just printing mine from the Autozone site, and laminated it with packing tape. It's much better to be able to reference from the card, than to just guess at what it should be based on what you remember from the last time you looked at the chart.I do have a couple complaints, but they aren't a big deal. I'd like it if they'd do it for the next version.First is, my old set had dummy connections to snap the quick disconnects on. The back of this set has the male threaded ports to thread the hose directly onto, but nothing to hook the quick disconnects to. Most people doing automotive work need the quick disconnects. Even if they just included a male quick disconnect fitting, that threaded into the male threaded posts on the back, would have been great.The second is the reference card. I printed and laminated my own. It would have been nice if that was included with the set.I'm not in love with the pump/can line adapter on the yellow hose. The other manifold sets I have screwed onto the pump and cans easily. This one, doesn't do it very gracefully. I'll probably swap in the yellow hose from another old set that broke.TL;DR, if you need a manifold set to fix your AC, this one will work fine. At the price, I can't complain. There are plenty of more expensive options, that provide the same functionality. Some of the competition sets have less features. Like no hoses, or no quick disconnects.

this is a nice set of gauges.. I am happy with how they work and fit my car. saved me a lot of money

Buen producto y hace muy buena funcion, yo he probado presiones para minisplits R22 y 410A y todo perfecto

Product was good, but make sure you get the right version that comes with a Can Tap adapter.

The air in my truck was weak. Went to WallyWorld and got a can of R134a with the gauge on it. Pumped in the entire can and the gauge never got to the middle of the green. Put these gauges on and found that the low side was twice as high as it should be. Reduced the low side to where it is supposed to be and now the air is working great. Can't believe that something of this seeming quality is so cheap. Wish I had bought this set years ago. Going to try them on the car next. Would recommend to anyone.
