568-417 URETHANE 90 ORINGS -PREM GRADE

Ordered as U90417, this is an AS568-417 clear Polyurethane (AU/EU) 90 Shore A O-Ring with an inside diameter of 3.475 in (88.27 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 4.025 in (102.24 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Polyurethane (AU/EU) offers long wear life in dynamic reciprocating service and exceptional abrasion resistance. The compound resists ozone, impact and shock loading, and petroleum oils. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). Exposure to prolonged humidity at elevated temperature or ketones will shorten service life.

Maintenance and OEM teams specify it across press and forming equipment, construction machinery, and mining and heavy equipment.

Reference part number U90417 when ordering; the item is sold individually. Nominal inside diameter is listed as 3 1/2 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
