As a material, Polyurethane (AU/EU) delivers long wear life in dynamic reciprocating service and exceptional abrasion resistance. It resists abrasion and wear, extrusion under high pressure, and ozone. Applications involving hot water and steam or acids and bases call for a different compound.

It sees regular use in high-pressure fluid power, hydraulic cylinders, and press and forming equipment.

L37503750625B ships individually. Review your operating media and conditions against this specification before installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
