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.
Flexible Stainless Steel Hoses
Flammable Gas Flash Arrestor—Factory Mutual Approved*
• Gas flow shuts off in the event of a flashback.
• Flame extinguished—flame front prevented from reaching the gas supply.
• No gas flow restriction under normal operating conditions.
*Approved for brass body servicing hydrogen, acetylene, propane, or natural gas only.
