Spring Energized PTFE face seal
Spring –loaded seals are designed for static,rotary and reciprocating applications in temperatures from cryogenic to 250℃;and pressures from vacuum to 100Mpa,to survive the most corrosive environment.
 
The design combines a “U”shaped spring or canted coil spring or Helical spring with a PTFE or UHMWPE-based seal jacket to achieve one of the most efficient and versatile sealing methods. The high strength stainless steel energizer provides strength and flexibility to control seal loading,even with temperature extremes,while the PTFE jacket provides the well known PTFE virtues of low friction,corrosion resistance,sealability and wear resistance.
