Single-Stage Argon/Nitrogen Regulator
The Harris 330-500-580 is a single-stage regulator built for high-pressure cylinders supplying argon or nitrogen. It features a brass body with a chrome-plated finish and a stainless steel diaphragm for durability. The unit connects via a CGA 580 inlet with a 0.965-14 male thread and provides a male 1/4 inch NPT outlet connection.
Suited for inert gas shielding and blanketing
This regulator suits welders and technicians who need a straightforward pressure control device for argon or nitrogen from standard high-pressure cylinders. The single-stage design reduces inlet pressure directly to the working outlet setting. Buyers requiring constant delivery pressure as cylinder pressure drops, or those needing compatibility with fuel gases or oxygen, should look at other equipment.
500 psig outlet pressure with 600 psig gauge
The regulator delivers a maximum outlet pressure of 500 psig, monitored by a gauge reading up to 600 psig. This range comfortably handles typical MIG and TIG shielding flow rates and general inert gas blanketing tasks. It runs out of headroom for applications demanding outlet pressures above 500 psig or for use with cylinder valve outlets other than CGA 580.

Questions about this item
What CGA-580 cylinder fitting does the 0.965-14 inlet connect to?
The regulator screws directly onto a CGA-580 high-pressure argon or nitrogen cylinder using its 0.965-14 male inlet nut.
Will the 1/4-inch male NPT outlet thread into my existing TIG torch hose?
Yes — the outlet is a standard 1/4-inch male NPT, so it accepts any hose or fitting with a matching 1/4-inch female NPT thread.
How do I confirm the outlet pressure is holding at the 500 psig maximum after installation?
Open the cylinder valve slowly, then watch the outlet gauge; the needle should stabilise at or below 500 psig when the downstream valve is closed.
