568-136 URETHANE 90 ORINGS -PREM GRADE

APG stocks the U90136, an AS568-136 clear Polyurethane (AU/EU) 90 Shore A O-Ring with an inside diameter of 1.987 in (50.47 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.193 in (55.7 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

Polyurethane (AU/EU) is specified here for long wear life in dynamic reciprocating service and exceptional abrasion resistance. It resists extrusion under high pressure, abrasion and wear, and petroleum oils. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service.

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

U90136 ships individually. Nominal inside diameter is listed as 2 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
