    Product Description

  • Viton® FKM (Lip code: V) fluoroelastomer premium lip material offers the widest temperature range and chemical resistance of all seal materials.
  • Fluoroelastomers resist most special lubricants and chemicals that can destroy nitrile, polyacrylates or silicones.
  • This premium material, with its superior resistance to abrasion and high temperatures, provides superior performance and wear.
  • Works in dry running applications but only for intermittent periods.
  • 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.

  • Many of Nationals metal cased seals are offered with Redi-Coat® rubberized coating which is applied over the seals bare metal case and helps fill in any minor bore imperfections upon installing the new seal.

  • 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.
