    Product Description

  • Teflon® PTFE (Lip code: T) has excellent dry running capabilities but comes with important caveats as well.
  • Low coefficient of friction.
  • Excellent chemical resistance.
  • Resistant to oxygenated hydrocarbon blends.
  • PTFE has poor abrasion resistance to dirty environments.
  • There is high thermal expansion with PTFE.
  • Due to the delicate nature of Teflon, care must be taken when handling the seal as PTFE has unforgiving "memory" and will retain deformation of the sealing surface if banged, nicked, creased or folded during installation.
  • It must be noted that although fluoropolymers such as FKM and PTFE are classed as resistant to high temperatures, they will thermally degrade on exposure to extreme temperatures (FKM @ 316°C/600°F) and (PTFE @ 371°C/700°F) and emit hazardous fumes containing hydrofluoric acid (HF).
  • In the unlikely event of such a high temperature incident, allow the components in question to cool, douse with limewater (Calcium hydroxide solution), and handle with PVC gloves until neutral pH confirmed, then discard.

  • Rubber cover over a metallic core offers an excellent combination of sealing ability and corrosion resistance.
  • The rubber elastomer outer covering tolerates thermal expansion as well as roughness in the housing bore.
  • Because of the rubberized covering on the seal, there will be no fretting/galvanic corrosion of the metal bore that the seal is pressed into.

  • Please note that not all product images are representative of the item being shown but are similar in appearance. Please refer to the seals technical specifications sheet provided in the image carousel for absolute confirmation before ordering.
