Harris KH1010 Argon Regulator

The Harris KH1010 is a single-stage specialty gas regulator designed for welding applications using argon, helium or nitrogen. It delivers a maximum outlet pressure of 250 psig from a supply rated up to 4,000 psig. The brass chrome-plated body houses a neoprene diaphragm and a knob control. This unit suits fabricators who need a dedicated regulator for inert shielding gases.

CGA 580 Inlet Constraints

The regulator connects via a CGA 580 male inlet sized 0.965 in.-14 NGO, which matches standard high-pressure cylinders for argon, helium and nitrogen. Outlet flow exits through a 1/4 in. male NPT fitting. Single-stage construction means outlet pressure will rise as cylinder pressure falls, so operators must monitor gauges during long welds. It is not suited for applications requiring constant delivery pressure without adjustment.

Installation Notes

Thread the CGA 580 nut onto the cylinder valve by hand, then tighten with a wrench to the manufacturer’s torque specification; the brass body and chrome finish resist galling but require clean threads. Connect the 1/4 in. NPT outlet to a compatible hose or flowmeter using thread sealant rated for inert gas. Common issues include leaks from damaged inlet seats or omitted sealant on the NPT joint. The unit ships new and restricted in California due to Proposition 65 chemical content.

Questions about this item

Which outlet-pressure version of the Harris KH1010 should I choose for argon, helium or nitrogen?

This regulator delivers a maximum outlet pressure of 250 psig, suitable for those gases.

What does the 250 psig outlet pressure mean when the regulator is installed on my cylinder?

It limits the working pressure downstream to 250 psig regardless of the 4,000 psig gauge rating.

How does the CGA 580 inlet with 0.965-14 thread affect what I can connect?

It mates directly to standard argon, helium or nitrogen cylinders with a male 0.965-14 NGO connection.
