The U70034 is an AS568-034 clear Polyurethane (AU/EU) 70 Shore A O-Ring measuring an inside diameter of 2.114 in (53.7 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.254 in (57.25 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
The material holds up against abrasion and wear, ozone, and extrusion under high pressure. Polyurethane (AU/EU) delivers very high tensile strength and load capacity, exceptional abrasion resistance. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C).
Common environments for this compound include mining and heavy equipment, construction machinery, and off-highway equipment.
This item is sold individually under part number U70034. Check the compound against your process media, pressure and temperature before committing to a design. 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.
