568-138 URETHANE 90 ORINGS -PREM GRADE

Ordered as U90138, this is an AS568-138 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 2.112 in (53.64 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.318 in (58.88 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Polyurethane (AU/EU) delivers very high tensile strength and load capacity, outstanding extrusion resistance at elevated pressure. The compound resists impact and shock loading, petroleum oils, and abrasion and wear. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). Exposure to ketones or prolonged humidity at elevated temperature will shorten service life.

Common environments for this compound include construction machinery, off-highway equipment, and hydraulic cylinders.

U90138 ships individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
