*568-123 URETHANE 90 ORINGS -PR GRADE

APG stocks the U90123, an AS568-123 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 1.174 in (29.82 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.38 in (35.05 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

It resists extrusion under high pressure, ozone, and petroleum oils. Polyurethane (AU/EU) delivers very high tensile strength and load capacity, exceptional abrasion resistance. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. It is not the right choice where acids and bases or ketones are present.

Common environments for this compound include construction machinery, off-highway equipment, and high-pressure fluid power.

Order part number U90123, sold individually. Nominal inside diameter is listed as 1 3/16 inch. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
