Harris KH1001 Carbon Dioxide Regulator

This single-stage regulator is designed for carbon dioxide gas control in welding and specialty gas applications. It suits technicians who need a dedicated CO₂ supply with a fixed outlet pressure setting.

Brass body with chrome-plated finish and neoprene

The inlet uses a male 0.825"-14 NGO connection matching CGA 320 cylinders while the outlet provides a male 1/4" NPT fitting. Maximum outlet pressure is 50 psig and the single-stage design delivers consistent flow without a second pressure reduction stage.

Knob control for direct pressure adjustment

No additional accessories or software are included with the regulator body. Buyers who need a flowmeter, hose or multi-gas compatibility will need to source those components separately.

Questions about this item

What does the 0.825"-14 NGO male inlet thread connect to?

It mates with a CGA 320 cylinder valve used for carbon dioxide supply tanks.

What clearance does the 1/4" NPT male outlet and knob-controlled single-stage body need?

The chrome-plated brass body with neoprene diaphragm requires enough panel or bracket space for the 1/4" NPT male outlet fitting and front-mounted adjustment knob.

How is the regulator installed and which step is often missed?

Thread the 0.825"-14 NGO male inlet into the CGA 320 cylinder valve, tighten with a wrench, then open the cylinder valve slowly to seat the neoprene diaphragm before adjusting the knob to the desired outlet pressure up to 50 psig.
