RX WELD Nitrogen Regulator with 0-600 PSI, CGA580 Inlet, 1/4-Inch Male Flare Outlet Connection, Nitrogen Tank Regulator with 5Ft Refrigeration Hose

This regulator is for the US market so won’t fit the nitrogen bottles purchased in the UK ,!

Not for HVAC. Only for welders

At first the regulator seemed like it was leaking and not working right, but eventually I got it to work. When you unscrew the valve, it does not automatically release pressure but instead will hold it. Maybe certain regulators always work like this, but I wasn't aware. So if you want to reduce pressure you'll need to vent it to the outside. Other than that, the regulator worked fine. I pressure tested copper refrigeration lines to just under 500 psi and it held without any leaks for over an hour. Definitely worth the money and will be keeping for future nitrogen needs.

C'est exactement ce dont j'avais de besoin pour tester les fuites sur ma thermopompe apres avoir installé la tuyauterie.

Muy buenos manómetros

EXCELENTE

dudaba de su funcionalidad por el precio, pero los tecnicos ya trabajaron con el y funcionó bien , y mucho mejor precio que uno local
