568-281 URETHANE 70 DURO ORINGS

U70281 is an AS568-281 clear Polyurethane (AU/EU) 70 Shore A O-Ring supplied with an inside diameter of 14.984 in (380.59 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 15.262 in (387.65 mm). In service, this 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. This material stands up to ozone, petroleum oils, and impact and shock loading. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. Verify compatibility before use with ketones or acids and bases.

You will find this material specified across hydraulic cylinders, high-pressure fluid power, and mining and heavy equipment.

U70281 ships individually. Nominal inside diameter is listed as 15 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.
