568-046 URETHANE 90 ORINGS -PREM GRADE

Ordered as U90046, this is an AS568-046 clear Polyurethane (AU/EU) 90 Shore A O-Ring with an inside diameter of 4.239 in (107.67 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 4.379 in (111.23 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Polyurethane (AU/EU) is specified here for toughness that outperforms conventional rubber compounds and long wear life in dynamic reciprocating service. The compound resists abrasion and wear, impact and shock loading, and petroleum oils. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. Verify compatibility before use with prolonged humidity at elevated temperature or hot water and steam.

It sees regular use in high-pressure fluid power, mining and heavy equipment, and press and forming equipment.

Order part number U90046, sold individually. Application requirements vary, so validate compatibility with your process conditions prior to 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.
