Horrible they lied about withstanding a pressure. I used it on machine that discharges nitrogen through 5 mm nozzles and pressure drops quickly

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.

This nitrogen regulator is solidly built and easy to use. The gauges are glycerine filled and have a smooth motion for reading pressure. All the knobs turn easily.

Makes it easy to find leaks in a/c systems. High quality. I got a used tank off marketplace and had it filled.

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.
