Review: The packaging was busted. But the shipping box was fine. So I'm assuming the packaging was busted before shipping. Don't know if it's been dropped or suffered a hit at some point. Sucks as it's a regulator, sensitive equipment.
Review: 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!

## 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

Buena calidad. Hace los que debe en los rangos que promete. Los manómetros me llegaron bien calibrados. Dudaba de su funcionalidad y durabilidad sin embargo va muy bien después de 4 meses. Pues ya más de dos años y totalmente satisfecho!!! Muy económico y aguantador.
