568-284 URETHANE 90 ORINGS -PREM GRADE

APG stocks the U90284, an AS568-284 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 17.955 in (456.06 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 18.233 in (463.12 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

As a material, Polyurethane (AU/EU) is valued for long wear life in dynamic reciprocating service and outstanding extrusion resistance at elevated pressure. This material stands up to ozone, petroleum oils, and abrasion and wear. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with acids and bases or hot water and steam.

Typical settings include off-highway equipment, mining and heavy equipment, and high-pressure fluid power.

U90284 ships individually. Nominal inside diameter is listed as 18 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
