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

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: -80°F to 250°F (-62°C to 121°C)

Certifications include:
NAS 1613 Rev 6

Features:

• Chemical resistance
