Ordered as U70407, this is an AS568-407 clear Polyurethane (AU/EU) 70 Shore A O-Ring with an inside diameter of 2.225 in (56.52 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 2.775 in (70.49 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
Polyurethane (AU/EU) is widely chosen for exceptional abrasion resistance and toughness that outperforms conventional rubber compounds. Expect good resistance to abrasion and wear, ozone, and impact and shock loading. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with acids and bases or hot water and steam.
Typical settings include press and forming equipment, high-pressure fluid power, and mining and heavy equipment.
U70407 ships individually. Nominal inside diameter is listed as 2 1/4 inch. 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.
