Polyurethane (AU/EU) is specified here for long wear life in dynamic reciprocating service and outstanding extrusion resistance at elevated pressure. Expect good resistance to abrasion and wear, petroleum oils, and extrusion under high pressure. Verify compatibility before use with prolonged humidity at elevated temperature or hot water and steam.

Maintenance and OEM teams specify it across hydraulic cylinders, mining and heavy equipment, and construction machinery.

L18705000375B ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
