Ordered as U70041, this is an AS568-041 clear Polyurethane (AU/EU) 70 Shore A O-Ring supplied with an inside diameter of 2.989 in (75.92 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 3.129 in (79.48 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
It resists impact and shock loading, abrasion and wear, and extrusion under high pressure. That behavior comes from the compound itself: Polyurethane (AU/EU) is widely chosen for very high tensile strength and load capacity, exceptional abrasion resistance. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with ketones or acids and bases.
Maintenance and OEM teams specify it across mining and heavy equipment, construction machinery, and high-pressure fluid power.
Order part number U70041, sold individually. Review your operating media and conditions against this specification before installation.
