Product Name Notes
for natural gas and refinery gas standards 0–300 psig inlet pressure range. 0–15 psig outlet pressure range. Supplied with 0–15 psig outlet pressure gauge, brass CGA 170 nut and nipple.
for use with 14-liter and 48-liter Scott/Air Liquide Transportable Gases Use the CGA 160 inlet connection with 14-liter Scott/Air Liquide Transportable Gases. Use the CGA 165 inlet connection with 48-liter...
Backpressure regulators can improve detector performance by preventing bubble formation in the detector flow cell. They also are useful in post-column reaction lines and between detectors and fraction collectors in...

Most stable outlet pressure control. Secondary pressure regulation not needed.
Oxidation-resistant, chrome-plated. Most stable outlet pressure control. Secondary pressure regulation not needed. Most widely used regulator. Less internal volume than stainless steel gas regulators.
Oxidation-resistant, chrome-plated. Use when there is secondary pressure regulation downstream. Identical gas purity protection as with dual-stage gas regulators.
Oxidation-resistant, chrome-plated. Use where you need to reduce the line pressure by 20 psig (138 kPa) or more. Same purity protection as high-pressure cylinder regulators.
Single-stage, stainless steel. Two pressure gauges and CGA-180 fitting. 3,000 psig maximum inlet pressure. Stainless steel diaphragm and Kel-F® seat. 1/8-inch tube compression outlet. Low internal volume: 3.03 cc.
Use when there is secondary pressure regulation downstream. Identical gas purity protection as with dual-stage gas regulators.
