568-106 URETHANE 70 DURO ORINGS

Part number U70106 is an AS568-106 clear Polyurethane (AU/EU) 70 Shore A O-Ring supplied with an inside diameter of 0.174 in (4.42 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.38 in (9.65 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to petroleum oils, impact and shock loading, and ozone. That behavior comes from the compound itself: Polyurethane (AU/EU) offers long wear life in dynamic reciprocating service, very high tensile strength and load capacity. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). Applications involving prolonged humidity at elevated temperature or ketones call for a different compound.

Maintenance and OEM teams specify it across mining and heavy equipment, high-pressure fluid power, and off-highway equipment.

Reference part number U70106 when ordering; the item is sold individually. Nominal inside diameter is listed as 3/16 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
