An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Polyurethane (AU/EU) delivers long wear life in dynamic reciprocating service and outstanding extrusion resistance at elevated pressure. The compound resists abrasion and wear, impact and shock loading, and petroleum oils. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service.
Maintenance and OEM teams specify it across press and forming equipment, high-pressure fluid power, and construction machinery.
