Ordered as U90916, this is an AS568-916 clear Polyurethane (AU/EU) 90 Shore A O-Ring supplied with an inside diameter of 1.171 in (29.74 mm), a cross section of 0.116 in (2.95 mm), and an outside diameter of 1.403 in (35.64 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.
Expect good resistance to extrusion under high pressure, impact and shock loading, and abrasion and wear. That behavior comes from the compound itself: Polyurethane (AU/EU) offers exceptional abrasion resistance and long wear life in dynamic reciprocating service. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). It is not the right choice where ketones or acids and bases are present.
Maintenance and OEM teams specify it across off-highway equipment, mining and heavy equipment, and hydraulic cylinders.
Stocked as U90916 and sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. 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.
