This o-ring is supplied in AS568-217 clear Polyurethane (AU/EU) 90 Shore A with an inside diameter of 1.171 in (29.74 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.449 in (36.8 mm), catalogued under part number U90217. It creates a positive seal at flange, piston and rod interfaces without added hardware.
Polyurethane (AU/EU) is widely chosen for long wear life in dynamic reciprocating service and toughness that outperforms conventional rubber compounds. The compound resists ozone, 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). Applications involving prolonged humidity at elevated temperature or hot water and steam call for a different compound.
You will find this material specified across press and forming equipment, off-highway equipment, and mining and heavy equipment.
Order part number U90217, sold individually. Nominal inside diameter is listed as 1 3/16 inch. Review your operating media and conditions against this specification before 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.
