144.5 X 2 EP70

Ethylene Propylene Oring

EPM, EPDM

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:

Excellent resistance to Skydrol and other phosphate ester fluids at high temperatures. Also exhibits excellent resistance to automotive brake fluids and steam.
