Harris 425-125-580 Gas Regulator

The Harris 425-125-580 is a single-stage gas regulator built for Argon, Helium and Nitrogen cylinders. It delivers a maximum outlet pressure of 125 psig from a 4,000 psig inlet gauge. The unit suits welders and technicians who need consistent flow control for shielding or inert gas applications.

Brass body with chrome plating and neoprene

The brass body carries a chrome-plated finish for corrosion resistance while the neoprene diaphragm manages pressure regulation. A T-handle provides manual adjustment. The inlet uses a male CGA 580 connection sized .965-14 NGO and the outlet presents a male 9/16-18 UNF fitting for standard hose attachment.

Replaces worn or mismatched single-stage regulators

This regulator upgrades setups where an older unit no longer holds steady outlet pressure or where the gas type or CGA fitting was incorrect. The jump is worth it when the current regulator leaks, drifts under load or cannot mate with a CGA 580 cylinder valve. It does not serve applications requiring two-stage pressure stability.
