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.

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.
