Harris KH1058 Two-Stage Regulator

The Harris KH1058 is a high-purity gas regulator built for cylinder mounting. It controls argon, helium and nitrogen through a two-stage design that delivers stable outlet pressure. A knob provides manual adjustment and the unit is rated for a maximum inlet pressure of 350 psig.

Suitable Gases and Pressure Limits

This regulator suits workshops that need precise low-pressure delivery for inert shielding gases. The maximum outlet pressure is 15 psig, so it will not serve applications requiring higher downstream pressure. Buyers needing compatibility with other gas types or different connection standards should look elsewhere.

Installation Notes and Common Issues

The inlet uses a 0.965 in.-14 NGO right-hand male thread and the outlet is a 1/4 in female tube fitting with right-hand threads. Verify that your cylinder valve and downstream hose match these exact specifications before fitting. The product carries California Proposition 65 warnings for cancer and reproductive harm.

Questions about this item

What cylinder fitting must I have for the 0.965 in.-14 NGO male inlet on this regulator?

The regulator requires a cylinder valve with a matching 0.965 in.-14 NGO female outlet, right-hand thread, rated for up to 350 psig inlet pressure.

Will the two-stage design maintain a steady 15 psig outlet if my supply cylinder pressure drops during use?

Yes, the two-stage construction reduces outlet-pressure variation as the cylinder empties, keeping delivery stable up to the 15 psig maximum.

How can I verify the regulator is delivering the set pressure after I connect it to my argon, helium or nitrogen cylinder?

Open the cylinder valve slowly, then read the outlet gauge; it should hold steady at or below 15 psig with no creep when the downstream valve is closed.
