Trade Names:
Excellent resistance to Skydrol® fluids used in commercial aircraft hydraulic systems. Also, recommended for hot
water, steam, and phosphate ester type hydraulic fluids. Also resistant to some acids, alkalies, and ozone. Not
recommended for petroleum fluids or diester lubricants. Temperature range: -65° to +300°F.
Ethylene Propylene (EPM, EPDM) (EPR)
PTFE
Aflas ®
Trade Names:
Resistant to petroleum oils, hydrocarbon fuels, oxygen, ozone, and weathering. Particularly recommended for hydraulic
systems where high pressures, shock loads, wide metal tolerances, or abrasive contamination is anticipated. Not
recommended for acids, ketones, and chlorinated hydrocarbons. Some urethanes are also sensitive to water and
humidity. Temperature range: -65° to +200°F.
Urethane (Polyurethane)
(FVMQ)
Nordel (E.I. DuPont) Royalene (Uniroyal) Epsyn (Copolymer Rubber)
Vistalon (Exxon Chemical) Epcar (B. F. Goodrich)
Trade Name:
White thermoplastic fluoroethylene resin offers a combination of qualities not found in any other material-chemical
inertness, heat resistance, low friction, dialectric strength, weatherability, zero water absorption, toughness, and
flexibility. Temperature range: -65° to +500°F.
Teflon® (E.I. duPont)
Trade Name:
Advantageous combination of high temperature, chemical and electrical resistance properties. Recommended for oils
and lubricants, hydraulic and brake fluids, transmission and power steering fluids, sour oil and gas (H2 S), amine
corrosion inhibitors, ozone, steam, acids, bases, alcohols, and a variety of other chemicals. Temperature range: -20° to
+400°F. (+600°F short term).

Teflon® Encapsulated
Seamless and uniform Teflon® FEP encapsulation which completely encloses a core material of either silicone or
Viton® elastomer. Matches the chemical and temperature resistance of solid PTFE O-Rings and possesses the
elasticity and recovery properties which are crucial in many sealing applications. Complete technical information on
Teflon® Encapsulated O-Rings is provided on pages 4 and 5.
Fluorosilicone
Good low/high temperature resistance. Excellent resistance to petroleumoils and fuels. Used in aerospace applications for
fuel systems and systems requiring resistance to diester base lubricants to 350°F. Due to limited strength and abrasion
resistance, this material is generally recommended for static applications only. Temperature range: -80° to +350/400°F.
