568-383 URETHANE 90 ORINGS -PREM GRADE

Ordered as U90383, this is an AS568-383 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 13.975 in (354.97 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 14.395 in (365.63 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Polyurethane (AU/EU) is specified here for long wear life in dynamic reciprocating service and toughness that outperforms conventional rubber compounds. The compound resists impact and shock loading, ozone, and abrasion and wear. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service.

Maintenance and OEM teams specify it across high-pressure fluid power, off-highway equipment, and mining and heavy equipment.

Stocked as U90383 and sold individually. Nominal inside diameter is listed as 14 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
