PTFE [TFE, Teflon® (E.I. duPont)]

White thermoplastic fluoroethylene resin offers a combination of qualities not found in any other material ─ chemical inertness, heat resistance, low friction, zero water absorption, toughness, and flexibility. Temperature range: -65° to +500°F.

Aflas®

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 (H2S), amine corrosion inhibitors, ozone, steam, acids, bases, alcohols, and a variety of other chemicals. Temperature range: -25° to +450°F.

Urethane (Polyurethane)

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. Temperature range: -65° to +200°F.

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 of the core elastomer which are crucial in many sealing applications.
