The U90277 is an AS568-277 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 11.484 in (291.69 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 11.762 in (298.75 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.
Polyurethane (AU/EU) is valued for long wear life in dynamic reciprocating service, very high tensile strength and load capacity. It resists impact and shock loading, petroleum oils, and extrusion under high pressure. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). Exposure to ketones or hot water and steam will shorten service life.
Common environments for this compound include press and forming equipment, mining and heavy equipment, and hydraulic cylinders.
U90277 ships individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
