Buna-N
Good oil resistance.
Viton® Fluoroelastomer
Used in applications requiring chemical and oil resistance.
Silicone
Excellent ozone, weather, detergent, and salt water resistance. Good high and low temperature resistance.
Neoprene
Weather and ozone resistant. Compatible with Freon.
PTFE
Most versatile resistance: acids, alaklies, synthetic lubricants, hydrocarbons, detergents, alcohol, refrigerants, and ketones.
EPDM (Ethylene Propylene)
Water, steam, and weather resistant.
FEP-Encapsulated
Perfect for sealing corrosive fluids. Virtually impervious to most solvents and chemicals.
Polyurethane
Excellent resistance to abrasion and tearing.
Kalrez® Perfluoroelastomer
Combines the resilience and sealing force of an elastomer with similar excellent chemical and temperature resistance of PTFE.
Fluorosilicone
Resists petroleum fluids.
Aflas
Offers excellent chemical, heat, electrical, and oil resistance.
Hytrel
Resists tears, abrasion, and corrosion.
Glass-Filled PTFE
Made of polytetrafluoroethylene (PTFE) with 20% glass content for increased wear resistance. Can handle higher pressures than standard PTFE.
