Carbon Dioxide Two-Stage Regulator
The Harris KH1017 is a two-stage specialty gas regulator built for carbon dioxide service. It provides stable outlet pressure through a brass body with chrome-plated finish and neoprene diaphragm. The unit carries CGA 320 inlet rating and is marked with California Proposition 65 warnings for cancer and reproductive harm.
Replaces Single-Stage Units
A two-stage design reduces pressure in two steps, so outlet pressure stays steadier as the cylinder empties. The jump is worth it when consistent flow matters for shielding gas or beverage dispensing and the supply pressure drops over a long shift. Single-stage regulators let delivery pressure rise as inlet pressure falls, which can affect weld quality or carbonation levels.
CGA 320 Inlet Constraint
The regulator accepts a male 0.965"-14 NGO inlet connection and delivers gas through a male 1/4" NPT outlet. Maximum outlet pressure is 50 psig while the gauge reads up to 4,000 psig. It cannot be used with cylinders that carry a different CGA number or thread form, so buyers needing argon, oxygen or mixed-gas service must select a regulator with the matching inlet standard.

Questions about this item
Will the 0.965-14 male inlet thread fit my CO₂ cylinder valve?
The regulator uses a CGA 320 male inlet sized 0.965"-14, which is the standard connection for carbon dioxide cylinders.
How do I set the outlet pressure without over-pressurising the 1/4 NPT male outlet?
Turn the control knob clockwise to increase pressure up to the 50 psig maximum; the two-stage design holds the set pressure steady as the cylinder empties.
When should I replace the neoprene diaphragm inside this brass body?
Replace the diaphragm if you notice pressure creep, gauge fluctuation or visible cracking during routine inspection.
