Motorcycle Fork Cartridge Rod Oil Seals

Teknik Cartridge Rod Seals

Cartridge Rod Seals

An internal damping cartridge cylinder sits in the middle of the outer case tubes inside most oil filled motorbike front forks. The suspension fluid can either be shared with the rest of the fork leg, or can be separately sealed – read more in our Closed vs Open Chamber Forks technical article.

Sealing rebound rods and preventing oil bypass in cartridge forks

  • Flexible lipped viton shaft seals and optional back-up rings seal oil between the rebound rod and cartridge bore
  • Keep damping consistent inside internal damping cartridge cylinders for predictable rebound and compression
  • Seals locate into machined alloy seal case heads top and bottom
  • Replace seals when fitting aftermarket compression & rebound adjustable fork cartridges or during rebuilds

Recommended Pairings

Consider matching seals and rebuilds with specialised tools such as Suspension Tools for correct fitment and service.
