Nitrogen Regulator Single Stage
The Harris 25GX-500-580 is a single-stage nitrogen regulator designed for gas control in welding and industrial applications. It features a brass body with a chrome-plated finish and a fibre-reinforced neoprene diaphragm. The unit delivers a maximum outlet pressure of 500 psig from a maximum inlet gauge pressure of 4,000 psig.
CGA 580 Inlet .965"-14 Connection
This regulator suits operators requiring a CGA 580 inlet connection with a male .965"-14 NGO thread for nitrogen cylinders. It provides a male 1/4 inch SAE 45-degree flared outlet for compatible hose fittings. Buyers using cylinders with different CGA numbers or outlet thread types should look at alternative regulators.
Maximum Outlet Pressure 500 psig
The factory-set maximum outlet pressure of 500 psig is the critical specification that determines whether this regulator matches the downstream equipment requirements. Verify that your application operates safely within this pressure limit before installation.

Questions about this item
How hot or noisy does the 25GX-500-580 get when running nitrogen all day?
The single-stage brass body with a fibre-reinforced neoprene diaphragm has no moving parts that generate heat or noise; it simply reduces cylinder pressure to a steady 500 psig outlet.
What hose or fitting must I already own to connect the 1/4 in SAE 45° flare outlet?
A 1/4 in SAE 45° flare male hose or pigtail is required; the regulator outlet is male, so the mating part must be female.
Will the .965"-14 CGA 580 inlet thread onto my existing nitrogen cylinder valve?
Yes — the inlet is a male NGO .965"-14 thread matching CGA 580, the standard connection for nitrogen cylinders in this region.
