Harris KH1049 Oxygen Regulator for Laboratory Use
The Harris KH1049 is a single-stage specialty gas regulator designed for oxygen service in laboratory environments. It features a chrome-plated brass body with a stainless steel diaphragm and includes both a diaphragm-type shut-off valve and a relief valve. The unit meets CGA E-4 standards for construction and performance.
Verify Cylinder Connection and Pressure Requirements
Before ordering, confirm that your gas cylinder uses a CGA-540 inlet connection compatible with this regulator. Ensure the maximum inlet pressure of your supply does not exceed 3,000 psi and that your application operates within the 0 to 15 psi delivery range. The outlet uses a 1/4 inch tube fitting for downstream connections.
Steady Low-Pressure Delivery Under Continuous Flow
Under sustained load, the single-stage design provides consistent pressure control within the 0 to 15 psi range for laboratory applications. The 2-inch supply pressure gauge reads up to 4,000 psi, allowing operators to monitor cylinder contents during extended use. The stainless steel diaphragm maintains regulation stability without the pressure decay common in high-flow bursts.

Questions about this item
Does the Harris KH1049 come with a CGA-540 cylinder connection and a 1/4 in tube fitting, or do I need to buy adapters separately?
The regulator includes a CGA-540 inlet connection for the cylinder and a 1/4 in tube fitting outlet, so no separate adapters are required for standard oxygen service.
How do I choose between the 0 to 15 psi delivery range and other models for laboratory oxygen work?
Select this model when your application requires precise low-pressure oxygen control up to 15 psi; the single-stage design and stainless steel diaphragm suit laboratory use.
What does the 3,000 psi maximum inlet pressure mean when the regulator is attached to a full oxygen cylinder?
It means the regulator is rated for cylinders filled up to 3,000 psi, and the 4,000 psi supply gauge will show the cylinder pressure as it drops during use.
