The material holds up against extrusion under high pressure, petroleum oils, and impact and shock loading. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. Verify compatibility before use with hot water and steam or prolonged humidity at elevated temperature.

Typical settings include hydraulic cylinders, construction machinery, and mining and heavy equipment.
