Ultra-HighPurity (UHP)StainlessSteelBodyGasRegulators
UHP stainless steel regulators are the standard for ultra-high-purity and corrosion-
resistant pressure regulation.Theyaremore easilypurgedof atmospheric components,
compared tobrass gas regulators,making them ideal for themost demanding applica-
tions. Stainless steel is especially useful in atmospheres of dry corrosive gases such as
hydrogen.

• Gas flow shuts off in the event of a flashback.
• Flame extinguished—flame front prevented from reaching the gas supply.
• No gas flow restrictionunder normal operating conditions.
*Approved for brass body servicing hydrogen, acetylene, propane, or natural gas only.
