Hydrogen CGA-350 regulator

The Harris KH1005 is a single-stage specialty gas regulator built for hydrogen cylinders with a CGA-350 inlet. It delivers a 0 to 125 psi outlet range through a 1/4 in hose-barb connection. The chrome-plated brass body and neoprene diaphragm suit laboratory gas-control tasks.

Installation notes

Thread the CGA-350 nut onto the cylinder valve and attach tubing to the 1/4 in hose barb; the outlet needle valve and relief valve are already fitted. A 2 in supply-pressure gauge reads up to 4,000 psi while the maximum inlet rating is 3,000 psi. Over-tightening the brass inlet can damage the seat, so use the correct wrench size and leak-test before use.

Sustained-load behaviour

The single-stage design means delivery pressure will rise as the cylinder pressure falls during extended runs. The 2.125 in body diameter and chrome-plated brass construction dissipate heat adequately for typical laboratory flow rates. The neoprene diaphragm maintains seal integrity across the 0 to 125 psi range without drift during long sessions.

Questions about this item

How do I confirm the regulator is delivering the correct pressure after installation?

Watch the 2 in delivery gauge; the needle should settle between 0 and 125 psi while hydrogen flows, and the 4,000 psi supply gauge will show cylinder pressure dropping as gas is used.

What components are included and what must I source separately?

The unit ships with an outlet needle valve and relief valve already fitted to the 1/4 in hose barb; you will need a CGA-350 cylinder and suitable hose or tubing for the outlet.

Which model should I select for laboratory hydrogen service at standard cylinder pressure?

The KH1005 is the single-stage chrome-plated brass regulator rated for 3,000 psi maximum inlet with a CGA-350 inlet connection, matching standard hydrogen cylinders used in lab applications.
