It is made of EPDM or Ethylene Propylene Diene Monomer, which is well-known for its excellent heat, ozone and weather resistance. EPDM is extremely resistant to water and steam and maintains its flexibility even at low temperatures. For this reason, it has a wide range of applications and is excellent for use outdoors.
EPDM features outstanding resistance to alkalis, acids and oxygenated solvents, but is not recommended for resistance to oil, gasoline and hydrocarbon solvents. You should use only silicone grease lubricants to maintain the life of the O-ring and preserve the watertight properties of your case. To maintain the top level protection of your case, damaged O-rings should be replaced.
