Two-Stage CO2 Regulator

The Harris KH1018 is a two-stage specialty gas regulator designed for carbon dioxide supply in welding and industrial gas applications. It reduces high cylinder pressure to a stable working level through two sequential reduction stages for consistent outlet delivery.

CGA 320 Brass Body with Chrome Finish

The regulator connects to cylinders using a CGA 320 inlet sized 0.965"-14 NGO male and provides a 1/4 inch NPT male outlet. Maximum outlet pressure reaches 125 psig while the gauges read up to 4,000 psig. A brass body with chrome plating and neoprene diaphragm handle the gas flow.

Replaces Single-Stage Units for Steady Flow

This model upgrades from single-stage regulators when outlet pressure must stay constant as cylinder pressure drops. It is not suited for gases other than carbon dioxide or for systems requiring higher outlet pressures than 125 psig.

Questions about this item

Which Harris CO₂ regulator model should I choose for a CGA 320 cylinder?

The KH1018 is built for carbon dioxide cylinders using the CGA 320 inlet, so it matches that connection directly.

What outlet pressure will I actually get from the 125 psig maximum rating?

The two‑stage design delivers a steady outlet up to 125 psig, keeping pressure stable as the cylinder empties.

How does the 0.965"-14 NGO inlet thread affect compatibility?

The male 0.965"-14 NGO inlet threads straight onto a standard CO₂ cylinder valve without an adapter.
