*568-121 URETHANE 90 ORINGS-PREM GRADE

Ordered as U90121, this is an AS568-121 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 1.049 in (26.64 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.255 in (31.88 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Polyurethane (AU/EU) delivers exceptional abrasion resistance and long wear life in dynamic reciprocating service. It resists ozone, abrasion and wear, and extrusion under high pressure. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). Exposure to prolonged humidity at elevated temperature or hot water and steam will shorten service life.

It sees regular use in high-pressure fluid power, off-highway equipment, and construction machinery.

U90121 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
