Harris KH1022 Hydrogen Regulator
The Harris KH1022 is a two-stage specialty gas regulator built for hydrogen service on cylinders with a CGA-350 inlet. It delivers a controlled outlet range of 0 to 125 psi through a 1/4 inch hose barb outlet with an integrated needle valve. The unit includes a relief valve and meets CGA E-4 standards for gas handling equipment.
Two-stage pressure control
Two-stage regulation reduces the cylinder supply pressure to the working range in two steps, so outlet pressure remains steady as the cylinder empties. The 2 inch supply gauge reads up to 4,000 psi while the delivery gauge covers the 0 to 125 psi range. Maximum rated inlet pressure is 3,000 psi, matching standard high-pressure hydrogen cylinders.
Chrome-plated brass construction
The body is machined from chrome-plated brass with a 2.125 inch diameter and uses a neoprene diaphragm for hydrogen compatibility. CGA-350 inlet threads connect directly to hydrogen cylinders without adapters. The 1/4 inch hose barb outlet accepts standard tubing, and the fitted needle valve allows fine flow adjustment at the point of use.

Questions about this item
How much heat or noise does the KH1022 produce during continuous hydrogen regulation?
The regulator body is chrome-plated brass and operates without a motor or fan, so it generates no measurable heat or audible noise during all-day use.
What existing fittings are required to connect this CGA-350 inlet to a hydrogen cylinder?
The inlet uses a standard CGA-350 connection rated for 3,000 psi max inlet pressure, matching the cylinder valve found on hydrogen specialty-gas cylinders.
Will the two-stage design maintain steady delivery pressure if my older single-stage manifold fluctuates?
Yes, the two-stage construction reduces delivery-pressure decay as cylinder pressure drops, keeping the 0 to 125 psi outlet stable even when upstream supply varies.
