Harris KH1019 Carbon Dioxide Regulator

The Harris KH1019 is a two-stage specialty gas regulator built for carbon dioxide service. It delivers a maximum outlet pressure of 250 psig through a male 1/4 in NPT outlet connection. The chrome-plated brass body and neoprene diaphragm suit industrial and laboratory gas control tasks.

Two-Stage Brass Construction With CGA 320 Inlet

The two-stage design reduces outlet pressure fluctuation as the cylinder empties. A CGA 320 male inlet fits 0.965"-14 nitrogen/CO₂ cylinder valves directly. Chrome plating on the brass body resists corrosion while the knob control allows straightforward pressure adjustment.

Knob Control and NPT Outlet for Direct Plumbing

The regulator ships with a knob-type control and a male 1/4 in NPT outlet ready for pipe-thread fittings. No additional adapters or hoses are included in the package. California Proposition 65 warnings apply for cancer and reproductive-harm chemicals present in the materials.

Questions about this item

What does the CGA 320 inlet on this Harris KH1019 regulator limit the outlet pressure to in practice?

The two-stage design delivers a maximum outlet pressure of 250 psig through the 1/4 in male NPT outlet, with the CGA 320 inlet rated for up to 4,000 psig supply pressure.

What are the exact thread specifications needed to mount this regulator to a CO₂ cylinder?

The inlet requires a male 0.965"-14 NGO connection (CGA 320) to mate with the cylinder valve; the outlet is a male 1/4 in NPT fitting for downstream hose or piping.

How is the Harris KH1019 installed on a CO₂ cylinder, and what step is often missed?

Thread the male 0.965"-14 NGO inlet (CGA 320) directly onto the cylinder valve by hand, then tighten with a wrench; the step often missed is leak-testing the connection with approved solution before opening the cylinder valve.
