Motorcycle Fork Sealing Rubber O-Rings

Fork O-Rings

All rebuildable motorbike front forks & rear shock absorbers need some basic shared parts – fasteners, teflon lined shaft collars or acetal rod bushes, mid-speed valve springs and rubber o-rings to keep oil & gas pressure sealed. These fork o-rings are used across fork caps, pistons, cartridge cases and axle lugs and should be renewed at every rebuild. Common types include Top Cap O-Rings, Free Piston O-Rings, Compression Piston O-Rings and the small seals used on Air Bleed Screws, Cartridge Seal Cases, Cartridge Rod Oil Locks, Axle Feet and Rebound Adjuster assemblies.

Fork O-rings for sealing and rebuilds

  • Maintain oil and gas pressure seals for predictable damping
  • Replace small wear seals on caps, pistons, cartridge cases and adjusters
  • Essential service items for every fork rebuild or tune
  • Compatible with cartridge kits, emulsion valves and axle lug seals

Recommended Pairings

Consider matching seals with Suspension Tools for accurate rebuilds and our Valving Shims when revalving your forks. For tech guidance see our Shim Factor Calculator, lock nuts and fasteners guide and suspension fluid weights table.
