Ordered as U90265, this is an AS568-265 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 7.734 in (196.44 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 8.012 in (203.5 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
Polyurethane (AU/EU) is specified here for toughness that outperforms conventional rubber compounds and exceptional abrasion resistance. It resists extrusion under high pressure, impact and shock loading, 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 prolonged humidity at elevated temperature or ketones.
Common environments for this compound include mining and heavy equipment, off-highway equipment, and high-pressure fluid power.
Reference part number U90265 when ordering; the item is sold individually. Check the compound against your process media, pressure and temperature before committing to a design.
