Harris KH1044 High Purity Gas Regulator Argon Helium Nitrogen Single Stage

SKU CH-E9DC-SB96W

Single-stage high-purity regulator for argon, helium and nitrogen cylinders with 350 psig maximum inlet and 50 psig outlet

  • Main materialHAWA
  • Product typeWelding Supplies
  • Single-stage design simplifies gas control for argon helium nitrogen
  • 350 psig maximum inlet handles high-pressure cylinders safely
  • 50 psig outlet limit protects downstream equipment from overpressure
  • ¼-inch tube-fitting outlet connects directly to standard welding hoses
  • .965-14 NGO male inlet fits common gas cylinders without adapters

Purpose and User

The Harris KH1044 is a high-purity gas regulator designed for argon, helium and nitrogen supply in single-stage operation. It suits welders and technicians who require clean gas delivery for TIG or MIG processes where contamination must be minimised.

Build Integration

This regulator mounts directly to a cylinder using a male 0.965-14 NGO right-hand inlet connection. A knob control adjusts outlet pressure up to 50 psig, delivered through a female 1/4-inch tube fitting. The single-stage design reduces component count and potential leak paths in the gas line.

Upgrade Context

It replaces older or dual-stage regulators when a simpler, single-stage unit is preferred for steady cylinder pressure applications. The jump is worth it when the workflow demands high-purity gas compatibility with argon, helium or nitrogen and a compact, knob-operated control. Buyers needing higher outlet pressure or multi-gas preset configurations should look elsewhere.

Questions about this item

At what inlet pressure does the regulator reach its 350 psig maximum rating?

The regulator is rated for a maximum inlet pressure of 350 psig, which is the highest supply pressure it can accept before the relief device activates.

How much heat or noise does the KH1044 generate during continuous all-day operation?

As a passive mechanical regulator with no motor or electronics, it produces no measurable heat or audible noise under sustained flow.

Which cylinder fitting must I already have to connect this regulator?

You need a cylinder equipped with a male 0.965 in.-14 NGO right-hand thread to match the regulator's inlet connection.
