A must have tool for A/C repair work.
With the rising cost of R134A, I finally broke down and purchased this regulator kit to use for checking A/C systems on medium and heavy duty trucks. I should have purchased a long time ago. Works great, and is another quality Mastercool product.

Best kit out there.
This is the best kit to use for charging a/c systems with nitrogen. You can mess around and build a kit like this with mixed results or just by this and be up and running same day without having to track down obscure fittings.

An Absolute Must for AC work
I use this pressure test regulator to test for leaks in both home and automotive ac. This regulator is high quality. I recommend if you want to make sure these is no leaks prior to charging with refrigerant.

worked as expected
Product worked as expected seals fit well and no leaks, you do need to tighten quite hard to get a good seal.

its ok but has a few problems
the high side adapter collar was stuck open, also the hose size connection is wrong to fit my manifold gauge set.

Well worth the money
The only thing that bothers me about this is the regulator adjustment screw feels cheap, it isn’t as smooth as I want, but I’m picky.I don’t do reviews often, but this one I have to. This kit is well worth the money. I’m a mechanic by trade, busy life/not enough time so I took the girlfriends SUV to a dealership to find a slow AC leak, I told them it holds a vacuum overnight and passes a vacuum leak test, that they need to use nitrogen, got blank stares at 2 different dealerships. Long story short, they wanted to replace a bunch of parts without properly diagnosing. I bought this kit and a bottle of nitrogen, found the leak in 10 minutes and fixed it (cracked manifold that bolts to firewall/evaporator). Counting having to buy a bottle of nitrogen and this kit, I still saved myself $900 in parts and labour from the dealership.

Works perfectly!!
Decided to Nitrogen test an A/C leak on my 2017 Ford Expedition. As soon as I pumped the Nitrogen in, the hissing sound started. Found the leak within seconds. Worth the money, solid construction, easy to use instructions. I would recommend this unit to anyone who needs a nitrogen test kit for their automotive use.
