Harris KH1051 chrome-plated brass oxygen regulator with CGA-540 inlet and two-inch gauges

Harris

Harris KH1051 Specialty Gas Regulator Oxygen CGA-540

SKU CH-S5DC-ZQ7NT

Single-stage oxygen regulator with CGA-540 inlet, 0–125 psi delivery range and chrome-plated brass body for laboratory use

  • Single-stage design simplifies gas control for laboratory oxygen use
  • CGA-540 inlet connects directly to standard oxygen cylinders
  • Chrome-plated brass body resists corrosion in high-purity applications
  • Stainless-steel diaphragm maintains consistent delivery pressure up to 125 psi
  • Built-in shut-off and relief valves add safety during operation

Oxygen Cylinder Regulator CGA-540

The Harris KH1051 is a single-stage specialty gas regulator built for oxygen cylinders with a CGA-540 inlet. It delivers adjustable outlet pressure from 0 to 125 psi through a 1/4 inch tube fitting outlet. The chrome-plated brass body measures 2.125 inches in diameter and houses a stainless steel diaphragm.

Laboratory and light industrial oxygen supply

This regulator suits users who need a compact, single-stage unit for laboratory or light industrial oxygen service where a CGA-540 cylinder connection is required. It is not intended for applications that demand dual-stage pressure stability or for gas services other than oxygen.

CGA-540 inlet with 0-125 psi delivery range

The defining specification is the CGA-540 inlet paired with a 0 to 125 psi delivery pressure range. This combination determines whether the regulator matches the cylinder valve and the pressure requirements of the downstream equipment.

Questions about this item

Will the CGA-540 inlet on the Harris KH1051 thread onto my existing oxygen cylinder valve?

The regulator is built with a CGA-540 inlet connection, which is the standard thread for high-pressure oxygen cylinders, so it will mate directly with your current tank valve.

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

Watch the 2 in supply-pressure gauge (0–4,000 psi) and the delivery-pressure gauge (0–125 psi); when both needles settle within your target range and the stainless-steel diaphragm shut-off valve holds without creep, the unit is operating as intended.

Does the Harris KH1051 come with tubing and fittings, or do I need to buy them separately?

The box includes the single-stage regulator body with its integrated diaphragm shut-off valve and relief valve, but the 1/4 in tube-fitting outlet requires you to supply your own compatible tubing and any downstream fittings.
