It is determined by the type of rubber material and storage conditions. Under the recommended storage conditions, the shelf life of seals varies by material. For example
Polyurethane, thermoplastic materials have a shelf life of 4 years;.
Nitrile rubber, hydrogenated nitrile rubber, neoprene rubber has a shelf life of 6 years; and
The shelf life of ethylene propylene rubber is 8 years.
The shelf life of fluoroelastomer, silicone rubber, fluorosilicone rubber is 10 years.
Perfluoroelastomer has a shelf life of 20 years.
Polytetrafluoroethylene is preserved indefinitely.
