Gas Regulators

Overview of Restek Ultra-High Purity (UHP) Gas Regulators

• Regulators feature metal-to-metal seals throughout for long-term leak-tightness.

• Metal diaphragm outlet valve ensures gas purity.

• Each regulator is helium leak-test-certifiable to 1x10

-8

scc/sec.

• Temperature range: -40 °C to 60 °C.

All regulators are rated to 3,000 psig (20,684 kPa) maximum

inlet pressure.

Inlet gauge:

0 to 4,000 psig (0–27,579 kPa)

Dual-Stage Ultra-High Purity Chrome-Plated Brass Gas Regulators

• 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.

Ultra-High Purity (UHP) Brass Body Gas Regulators

UHP brass regulators are the best choice when using ultra-high purity carrier gas for

sensitive GC applications using MS, PID, or ECD detection methods. They feature

reduced internal dead volume relative to stainless steel bodies. The metal valve dia-

phragm ensures leak-free shutoff. Oxidation-resistant chrome plating maintains a like-

new appearance.

Note: CGA fittings are for U.S. use; DIN fittings are for European use; BS fittings are for use in the UK.

All regulators are rated to 3,000 psig (20,684 kPa) maximum

Single-Stage Ultra-High Purity Chrome-Plated Brass Gas Regulators

• Oxidation-resistant, chrome-plated.

• Use when there is secondary pressure regulation downstream.

• Identical gas purity protection as with dual-stage gas regulators.

Note: CGA fittings are for U.S. use; DIN fittings are for European use; BS fittings are for use in the UK.

Ultra-High Purity Chrome-Plated Brass Line Gas Regulator

• 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.
