Swagelok
This company has introduced a new low-temperature sealing option for its RHPS Series of pressure regulators (photo). Composed of low-temperature-resistant nitrile material, these new seals are designed to maintain a strong seal in cold climates and applications where significant cooling occurs due to high pressure drop, even in environments with extensive presence of hydrocarbons, where climate control may not be an option. The new sealing options have minimum temperature ratings of: –49°F (–45°C) for configurations rated up to 70.0 bars; –40°F (–40°C) for configurations rated up to 400 bars; and –4°F (–20°C) for configurations rated above 400 bars. — Swagelok Co., Solon, Ohio
