Have used on 8-10 vehicles so far and has help up very well! No issues and gauges are on point good buy at a decent price

The gauge block is very hefty and I was surprised by its weight. If it drops it will surely ding the fender easily. The fittings are of decent quality along with the heavy hoses. Valve knobs all are metal open close smoothly. The only thing I did not like there was no resistance when turning at all and made me think sealing at the stem would leak but all seemed ok. The hose end valves were heavy metal having resistance of a tight seal on the stems. The hoses were flexible but solid, I could not squeeze the hose to flatten at all. The plastic case holds everything while it’s not assembled but it will not accommodate a fully assembled with hoses device where you have to disassemble to store in the case. Even if you remove the foam cutouts you still can’t store it assembled, not big deal to hang it assembled but it can collect dust but don’t count on storing it assembled in the case. Tested it and all seemed to work.

After years of using the little single gauge-on-the-can deals to top off AC systems I finally decided to be an adult and buy a real AC manifold gauge set. I did have to purchase another R134 can tap to match the (crappy annoying) new cans that are the norm now, but for the money it's no big deal imo. The hoses are good, the case is fine, the valves seem to work well and nothing leaks when properly assembled. The only gripe is it's a bit hard to fit everything back in the case. If you're using this regularly, you'll likely hang it on the wall like every other AC tech for the last umpteen decades has, and if you're a home-gamer you can leave one hose out or take the extra time to get them in there. Again, no biggie. All in all, I'm totally happy for the price, I wouldn't bet on using it five times a day every day but for the occasional AC job during the season? No problem.

I bought this manifold set to replace the old robyn air that got broken during a move.I’m pretty happy with how this manifold works.I have noticed that the fittings do come loose on the manifold and the quick connectors, but I will have to give them the benefit of the doubt for being new.I had no problem with the quick connectors sealing it all went together very quick and easy and the quick connectors fit the line fittings like a champ no leaking from anywhere.Yes the case could be a little bit better where the hoses go but it’s not a problem or a deal breaker for me.I like the aluminum knobs on it, it looks and feels pretty sturdy and well made.Have used it to evacuate and recharge a few R134A automotive AC systems now it will hold a 30ilb vacuum at the manifold with the quick connectors closed and 28-29ilb on the vehicle with the quick connectors open and the system drown down.I evacuated the systems for 45mins each and let them sit for 1hr on a closed system to check for leaks then recharged the system and all was good and done!Yes I would have to recommend this manifold set to anyone interested in getting a reasonably priced manifold set,It’s worth the money.Hope that this review helps you

Update: The connectors are garbage. I was able to sucessfully charge a '92 Corvette, and managed to get the gage set on to my 15 silverado to see how they fit because I was having trouble getting them to connect and disconnect. I got them on, but the low side was stuck on the truck. I fiddled with it for about 1/2 hour and it finally came loose. Skip ahead to today and I can't even get that stupid low side connector to connect to my 05 Camry. The high side did connect but the low side even feels wrong when you're starting it onto the stem, much less trying to force it on. I'm not aware of different sized couplers other than the high side being different than the low, but this low side connector seems a little too small in general. The gages work great. The couplers are absolute garbage, and I'm searching for new ones somewhere if I can find them.Original Post: First impression: I went out on a limb and bought this less expensive manifold gauge set. I'm pleased with it. The connectors are a little tricky, especially the high side. But they do connect and come off. You just have to work them a little bit. The valves all seem to be of decent quality as well as the gauges. It's nice having 4 hoses and valves although it's not really necessary. The yellow has a bleed off valve at the top - nice. The gauges read into the negative for measuring vacuum as well. Really handy for checking to ensure the vacuum is holding (Making sure there are no leaks before charging). I actually left all the valves open and there were no leaks, meaning all the connectors held vacuum too. So they seal nicely. It comes with all kinds of adapters and I was able to make all the connections I needed, including to the vacuum pump I purchased. It was especially nice not spending hundreds on a set like this.Update after about a month of use: I used this a handful of times while working on my '92 Corvette. Finally got the A/C system working and blowing ice cold air. However, unlike when I first started the project (Almost complete A/C system overhaul) the high side gauge didn't seem to be reading anymore. I figured maybe it could be the r134a retrofit adapter on the car, maybe the valve wasn't letting refrigerant through for the gauge to read. So I figured I'd test it on my 2015 Silverado. This truck Is practically new, and comes factory with R134a so it has correct and quality ports. I again had trouble connecting the connectors, especially the high side connector. It finally clicked in to place. The gauge worked correctly though. Then it was time to disconnect and I couldn't get the connector off. I fought with it for about 1/2 hour and got in a little bit of a panic because this truck is still under warranty and my daily driver. I can't have a connector stuck on there. Finally, with a pair of channel lock pliers it miraculously came loose with a bit of twisting, finagling, and forcing.I don't know where this gauge set is made as I can't find that info anywhere on this site or on the product itself. I'm leery of Chinese products these days. I can't really say the quality of this is that poor but the connectors really concern me. I would think a good quality set of connectors wouldn't have issues like this. I didn't bother contacting Orion Motor Tech about this because I'm not sure I want a replacement connector as I'm not really convinced the quality of the actual connectors is there and since they are screw on I might look for a quality pair of connectors to purchase elsewhere instead. I've used the plastic connectors on the cans before and never had issues like this. That's with cheap plastic connectors.Really the only reason I didn't give this 5 stars is because of the trouble I've had with the high side connector primarily, and the fact that it was stuck on my truck was quite concerning. If this set had better connectors, I would recommend this to anyone all day long. However, I do feel comfortable recommending it as a less expensive alternative to a professional set and a person could buy a set of higher quality connectors for it as I likely will.

As a retired ASE Master tech I can give an honest appraisal of the charging manifold. It is of similar quality to the equipment I used over 40 years purchased from major tool truck. However the refrigerant can tap is less than useless as it will not stay on the can or leaks if it does. I lost 3 cans of refrigerant trying to make it work and gave up trying for fear of losing more.

Buen producto. Buena calidad. Lo que se necesita.

Used these to install a few heat pumps on various buildings around my property, work great and have the adapters for 410a hookups.

These dials are hard to see with the blue colour numbers. Other than that - quality unit

Buen material resistente y cumple con la descripción

Nicely made and at a great price. Suits a professional.
