O-ring detail

Each Peli case comes with an o-ring in the lid to seal out any water, dust or debris. The o-ring maintains a watertight, dust-proof seal that protects the precious cargo you carry inside.

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.

O-Ring

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.
