*568-153 URETHANE 70 DURO ORINGS

U70153 is an AS568-153 clear Polyurethane (AU/EU) 70 Shore A O-Ring measuring an inside diameter of 3.487 in (88.57 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.693 in (93.8 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Polyurethane (AU/EU) is specified here for very high tensile strength and load capacity, toughness that outperforms conventional rubber compounds. This material stands up to petroleum oils, impact and shock loading, and ozone. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). Applications involving ketones or prolonged humidity at elevated temperature call for a different compound.

Common environments for this compound include press and forming equipment, mining and heavy equipment, and off-highway equipment.

This item is sold individually under part number U70153. Nominal inside diameter is listed as 3 1/2 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
