Parker Hannifin Polyurethane (AU/EU) Elastomers
Parker Hannifin Polyurethane elastomer materials are designed for sealing applications requiring exceptional abrasion resistance, high tensile strength, extrusion resistance, and mechanical durability. Polyurethane, commonly identified as AU or EU depending on polymer chemistry, is widely used in O-rings, hydraulic seals, pneumatic seals, U-cups, backup rings, scrapers, wipers, custom molded parts, and dynamic sealing systems operating under high pressure and severe wear conditions. These materials are commonly specified in hydraulic cylinders, heavy equipment, fluid power systems, mining equipment, industrial machinery, and mobile hydraulic systems where standard elastomers may wear prematurely.
Canyon Components supplies high quality equivalents to many Parker Polyurethane elastomer compounds used throughout industrial and hydraulic sealing systems. Our team supports replacement O-rings, hydraulic seals, gaskets, scrapers, and custom molded sealing components manufactured from Polyurethane compounds for high wear and high pressure applications. We also provide engineering support for extrusion resistance, dynamic sealing optimization, and abrasion resistance evaluation.
