Orion Motor Tech 5FT AC Diagnostic Manifold Freon Gauge Set for R134A R12

Fantastic

Perfect A/C manifold gage,great price,I will use it this summer to check ally units

My evaporator core sprung a leak and after getting a couple of quotes, I decided a DIY fix was in order. This manifold gauge set wasn't my first choice, the other was sold out, but in hindsight this set has 1 ft longer hoses which made the AC work much easier.I had no trouble putting it together or hooking it up, the high side slid right on without any struggle. Seals were all good and I was able to successfully vacuum test my work for 12 hours without any leakage in the system or the gauges/hoses. Recharging the system was a breeze with the can tap adapter (not included!) and I felt much better doing the recharge with the gauges versus the prior work I've done with a single low side can tap and gauge.The high side connector did indeed stick after running the system for 30 minutes while I recharged the system and the root cause is very clearly thermal expansion. If I hook up the system when the system and car are cool, it pops right off without issue. Once the car and the system heat up, the connector and hoses heat up and then it becomes more difficult. In my case, I waited 5 minutes and the quick connect released without much fuss. I'm sure there is an engineering solution to this problem, but for the price I'm ok with waiting a few minutes. It gave me an excuse to have a beer and celebrate a successful AC repair!

I received my A/C gauge set promptly. It is a good quality set for price point. The r134 high side adapter which is included had an issue. I emailed the company and immediately received a response seeking to resolve the problem. I took a picture of the issue, sent it in and instantly received a resolution without hesitation. Exactly the kind of service you hope for. I will buy from them again. The product works perfectly.

The manifold worked very well except for one issue. Whenever I would move the hoses around to shake the refrigerant can or for whatever other reason the threaded fittings loosened and resulted in leaks of the refrigerant.In other words, the fittings seal properly finger tight and there is no leaks until you start moving the hoses around. Next time I use it I'll have to find a way to prevent the threaded fittings to loosen up.

Look like good quality, haven't used yet
