10.77 X 2.62 PU90

Polyurethane Oring

AU, EU

Shore A Description:

The hardness of rubber compounds is measured by the Shore A durometer; the higher the durometer, the harder the compound. Softer compounds stretch easier and seal better on rough surfaces. Harder compounds offer greater abrasion resistance and resistance to extrusion.

60 Shore A is softer than 70

70 Shore A is the standard

90 Short A is very stiff

Specs:

Exhibit high tensile strength, making them the toughest of the elastomers. Compression set and heat resistance are inferior to other elastomers such as nitrile.

Material:

AU (Polyurethane)

Standard Service Temperature: -65°F - +212°F

Application:

Petroleum Fluids, Ozone, Abrasion Resistant, Drive Belts, Poor Compression Set

May be suitable for hydraulic applications which exhibit abrasive contaminants or shock loads.

*Polyurethane unlike other elastomers tend to revert or soften when exposed to over temperature situations).*

Not Compatible With: Hot Water, High Temperature, Brake Fluids, Acids
