Nitrogen regulator with CGA-580 inlet
This single-stage regulator controls nitrogen flow from a high-pressure cylinder. It is built for general-purpose welding and industrial gas-handling tasks. The brass body and stainless-steel diaphragm provide corrosion resistance. UL listing confirms compliance with recognised safety standards.
Delivery pressure up to 275 psi
The outlet pressure adjusts from zero to 275 psi for most shielding and purging jobs. A 2 1/2-inch supply-pressure gauge reads up to 4 000 psi, while the maximum rated inlet pressure is 3 500 psi. An external relief valve protects downstream equipment from over-pressure.
CGA-580 cylinder connection
The inlet nut fits standard nitrogen cylinders using the CGA-580 thread. The outlet uses a 5/8-inch -18 right-hand internal thread for hose or torch attachment. Nickel-plated bonnet and 3.25-inch body diameter complete the mechanical interface.
