Harris KH1128 High Purity Gas Regulator Argon Helium Nitrogen Single Stage

SKU CH-6188-K6V4D

Single-stage high-purity regulator for argon, helium and nitrogen cylinders with 350 psig maximum inlet and 15 psig outlet pressure

  • Main materialHAWA
  • Product typeTraffic & Parking Lot
  • Single-stage design simplifies gas control for argon, helium and nitrogen
  • Maximum inlet pressure of 350 psig handles high-pressure cylinders safely
  • Outlet pressure adjustable up to 15 psig for precise low-pressure delivery
  • 965 in.-14 NGO male inlet fits standard high-purity gas cylinders
  • 1/4 in. tube-fitting outlet allows quick, leak-tight hose connections

High-Purity Single-Stage Regulator

The Harris KH1128 is a new single-stage regulator built for high-purity gas delivery. It accepts argon, helium or nitrogen from a cylinder source and reduces pressure through a knob control. The unit mounts directly to a cylinder with a male NGO inlet.

Check Cylinder Pressure and Fittings

Verify your cylinder supplies a maximum inlet pressure of 350 psig and uses a .965-14 right-hand thread. The outlet provides a female 1/4-inch tube fitting at up to 15 psig. Ensure your downstream equipment matches this connection and pressure range.

Replaces Multi-Stage or Lower-Purity Units

This regulator replaces older single-stage models lacking high-purity compatibility or multi-stage units where single-stage control is sufficient. The step up is worth it when argon, helium or nitrogen purity is critical and inlet conditions stay within the 350 psig limit.

Questions about this item

What comes in the box with the Harris KH1128 regulator and what must I buy separately?

The regulator ships as a single unit; you will need to supply a compatible cylinder with a 0.965-14 NGO male inlet and 1/4-inch tube fittings for the outlet.

Which outlet pressure version of the KH1128 should I choose for argon, helium or nitrogen?

This model is factory-set to a maximum outlet pressure of 15 psig, so select it when your process requires low-pressure delivery of those gases.

What does the 350 psig maximum inlet pressure mean when the regulator is on a real cylinder?

It indicates the regulator can safely handle cylinder pressures up to 350 psig; do not connect it to sources exceeding that limit.
