70 Durometer

Silicone O-Rings are excellent seal materials for extreme temperature in static applications. Outstanding flex and fatigue life, very good for ozone and UV radiation, insulating properties, and physiologically neutral. Excellent heat and compression resistance, excellent flexibility, good electrical insulator. Excellent resistance to oxygen, ozone and sunlight, animal and vegetable oil and grease. Resistance to fungal and biological attack. Not recommended for dynamic application since it has low strength and poor abrasion resistance & high gas permeability. Also not recommended is use with concentrated solvents, oils, concentrated acids, diluted sodium hydroxide, hydrocarbon based fuels, aromatic mineral oil or aromatic Hydrocarbons (benzene, toluene), aromatic mineral oil, acids and alkalis, Superheated water or steam over 250 F.
