In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
Polyurethane (AU/EU) is specified here for toughness that outperforms conventional rubber compounds and outstanding extrusion resistance at elevated pressure. The compound resists petroleum oils, ozone, and abrasion and wear. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C).
It sees regular use in press and forming equipment, hydraulic cylinders, and mining and heavy equipment.
