Harris KH1025 Two-Stage Regulator
The Harris KH1025 is a two-stage specialty gas regulator designed for argon, helium and nitrogen supply. It reduces cylinder pressure to a maximum outlet of 50 psig through a chrome-plated brass body with a neoprene diaphragm. The unit suits laboratory, welding and industrial gas-handling tasks where stable delivery pressure is required. It is not intended for oxygen, fuel gases or high-flow applications needing larger port sizes.
Thermals Noise and Power Draw
As a passive mechanical pressure-control device the regulator generates no heat, consumes no electrical power and produces no audible noise during normal operation. Pressure reduction occurs through the two-stage piston and diaphragm assembly without fans, electronics or external energy input. The chrome-plated brass body dissipates any minor temperature change from gas expansion naturally. No thermal management or power supply is involved.
CGA 580 Inlet and 1/4 NPT Outlet
The supplied CGA 580 male inlet fits standard argon, helium and nitrogen cylinders with a 0.965-14 thread. A 1/4 inch male NPT outlet provides a direct connection for hose or tubing assemblies. The knob-adjusted control allows outlet pressure setting up to 50 psig without additional tools. Buyers needing other gas services, higher outlet pressures or different inlet standards must source alternative regulators.

Questions about this item
How do I install the KH1025 regulator on a cylinder and what step is often missed?
Connect the male NGO 0.965-14 inlet to a CGA 580 cylinder valve, then tighten with a wrench; the step often missed is using a fresh PTFE tape or approved sealant on the taper threads to prevent high-pressure leaks.
What maintenance or replacement will the KH1025 need over time?
The neoprene diaphragm and internal seals degrade with gas exposure; plan to rebuild or replace the regulator every two to three years, or sooner if outlet pressure drifts above the 50 psig set point.
What limit appears first when the KH1025 runs continuously at high flow?
The two-stage design holds outlet pressure steady until cylinder pressure drops near the 50 psig maximum outlet rating; at that point delivery pressure falls off and the regulator can no longer maintain the set flow.
