Ultra-High Purity (UHP) Stainless Steel Body Gas Regulators
UHP stainless steel regulators are the standard for ultra-high-purity and corrosion-
resistant pressure regulation. They are more easily purged of atmospheric components,
compared to brass gas regulators, making them ideal for the most demanding applica-
tions. Stainless steel is especially useful in atmospheres of dry corrosive gases such as
hydrogen.
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)
Outlet assembly: diaphragm valve,

Dual-Stage Ultra-High Purity Stainless Steel Gas Regulators
• Most stable outlet pressure control.
• Secondary pressure regulation not needed.
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 Stainless Steel Gas Regulators
• 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.
International Fittings
All gas regulators are available with the following BS (British Standard) and DIN (German Industrial
Standards Organization) connections. Please contact your local Restek representative for more
information.
