Review: Great price, well constructed, works perfectly! - I needed a high pressure nitrogen regulator for my shop. It was for light-duty applications. Local stores had only very expensive regulators, so I took a chance on this one. It arrived quickly, installed easily, and works perfectly. I couldn't be happier!
Review: Nice regulator! - Nice product, use this everyday for hvac pressure testing. Going strong, quality product. Seems like i can get more out of the bottle with the higher psi.

## Questions & Answers

**Q: How do you adapt the 1/4" Male Flare Outlet Connection to 1/4" NPT fittings?**
A: just unscrew the flare connection from the valve body . I believe the body is taped for 1/4" npt

**Q: Could I attach an Argon flowmeter to this and use a gas scale factor for N2 flow?**
A: I don't know, only use mine to fill my nitrogen shocks on my buggy.

**Q: What is the max inlet PSI rating?**
A: I believe the guage goes to 4000 psi but the bottle I use is only 2000 psi

**Q: Can it be used for air compressed pressure regulation?. I need to reduce an 600 psi inlet air to 0-150 psi.**
A: No , the fittings on a nitrogen tank are different than those of a co2 tank
