Ethylene Propylene 80 Durometer O-ring, Mil/aero (EM163-80)

 

产品概况：

 

Parker's 80 durometer black EPDM, EM163-80, is a terpolymer of ethylene and propylene with a diene third monomer used for cross linking. This is particularly useful when sealing phosphate-ester hydraulic fluids and in brake systems that use fluids having a glycol base.

 

Temperature range: -70°F to 250°F (-57°C to 121°C)

 

Certifications include:

NAS 1613 Rev 6
