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)
