EPDM (Ethylene Propylene Diene Monomer) gaskets are made from synthetic rubber and are known for their excellent weather and ozone resistance. EPDM rubber’s temperature resistance is another great benefit, offering a solid temperature range of as low as -60° Fahrenheit and up to 300° Fahrenheit.
EPDM rubber is not particularly well know for use in applications where there is direct contact with petroleum-based products as it has poor resistance to oils, greases, and fuels.
