Ordered as U70408, this is an AS568-408 clear Polyurethane (AU/EU) 70 Shore A O-Ring built to an inside diameter of 2.35 in (59.69 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 2.9 in (73.66 mm). The 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, long wear life in dynamic reciprocating service. It resists ozone, abrasion and wear, and impact and shock loading. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). Applications involving prolonged humidity at elevated temperature or acids and bases call for a different compound.
Common environments for this compound include mining and heavy equipment, high-pressure fluid power, and construction machinery.
Stocked as U70408 and sold individually. 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.
