Swagelok (Solon, OH) has announced the release of a new low-temperature seal option. The new seal, a product expansion for the company’s RHPS Series pressure regulators line, is designed to maintain a strong seal in cold climates and applications where significant cooling occurs due to high pressure drop. Comprised of low-temperature-resistant nitrile material, these regulator components are ideal for use even in environments with extensive presence of hydrocarbons, such as at large industrial gas suppliers’ facilities where climate control may not be an option.
New low-temperature, nitrile-based seal, diaphragm/piston O-ring, and seat seal options will be available immediately on all regulator configurations in the RHPS Series pressure regulators product line. These new options have a minimum temperature rating of:
- -49°F (-45°C) for configurations rated up to 1015 psig (70.0 bar)
- -40°F (-40°C) for configurations rated up to 5800 psig (400 bar)
- -4°F (-20°C) for configurations rated above 5800 psig (400 bar)
