High-Pressure Regulator for Inert Gases

The Harris KH1114 is a single-stage regulator designed for argon, helium and nitrogen cylinders. It reduces inlet pressure up to 3,000 psig to a maximum outlet of 1,500 psig. The unit suits welders and technicians who need a fixed high-pressure delivery for gas-shielded processes.

Cylinder Mount and Connection Limits

The regulator mounts directly to a cylinder using a male NGO inlet with 0.965-14 right-hand threads. Outlet flow exits through a female 1/4-inch tube fitting, also right-hand. The single-stage design means outlet pressure will rise as cylinder pressure falls, so it is not suited for applications that demand constant pressure throughout the cylinder life.

Installation Notes and Common Issues

A wrench tightens the inlet nut to the cylinder valve; the knob adjusts delivery pressure. Leaks usually come from a missing or damaged inlet gasket or from over-tightening the tube fitting. The product carries a California Proposition 65 warning for chemicals linked to cancer and reproductive harm.

Questions about this item

Which gas types does the KH1114 regulator support?

The regulator is compatible with argon, helium and nitrogen cylinders.

What outlet pressure will I actually see at the torch when the inlet reads 3,000 psig?

The single-stage design delivers a maximum outlet pressure of 1,500 psig, so the torch sees up to that level regardless of the full cylinder pressure.

What does the 0.965-14 NGO inlet connection mean for cylinder fitment?

It matches a standard right-hand male cylinder valve with 0.965-14 NGO threads, so the regulator threads directly onto compatible argon, helium or nitrogen cylinders without an adapter.
