Seals' Spring-energized Teflon® Seals are used for linear or reciprocating rod and piston sealing applications, for rotating shafts as rotary seals, and for static and face sealing applications.

　　They are typically used in areas where elastomeric seals cannot meet the frictional, temperature, or chemical resistance requirements of the application. Seals made of Teflon have exceptional resistance to high temperature, chemical reaction, and corrosion, and provide the lowest coefficient of friction of all sealing materials.

　　Compared to other elastomeric sealing materials (e.g. Polyurethane, Nitrile and Viton Rubber), Teflon is a plastic material and offers little or no memory after being compressed; therefore, seals made out of Teflon® need to incorporate an energizing element made of an elastomer material, usually rubber (rubber-energized) or a metal spring (spring-energized).

　　Seals is utilizing a variety of Teflon (PTFE, Fluoropolymer) compounds, spring types and materials, lip configurations, and seal designs to meet the requirements of the most demanding seal environments.

　　Maximum values depend on seal material, seal configuration and working environment. For maximum seal life expectancy, do not operate your seal beyond 50% at the combined limits of the working conditions.

　　Utilizing advanced materials designed specifically to offer our customers maximum durability, we manufacture the widest array of seals to meet the full range of industry fluids, temperatures, surface speeds and pressures.
