Ordered as U70159, this is an AS568-159 clear Polyurethane (AU/EU) 70 Shore A O-Ring with an inside diameter of 4.987 in (126.67 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 5.193 in (131.9 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against impact and shock loading, abrasion and wear, and petroleum oils. Polyurethane (AU/EU) is specified for long wear life in dynamic reciprocating service and toughness that outperforms conventional rubber compounds. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C).

Typical settings include construction machinery, high-pressure fluid power, and mining and heavy equipment.
