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

## Questions & Answers

**Q: How many pounds of pressure will this have at the output?**
A: Great question!

The maximum this pump will output is 1000psi which is the far end or the dangerous portion of the gauge. Standard safe zone for the pressure is at 500psi before you get into the warning area. If you have any other questions please feel free to let us know and we will be more than happy to assist you.

Have a great day!
