The RISK RL332–RL341 Bicycle Suspension Fork Dust Seal Press Tool Series is designed for installing dust seals and oil seals during suspension fork maintenance. It helps press fork seals evenly and securely into the fork lower legs, making suspension service cleaner, safer, and more efficient.

Available in multiple sizes from 30 mm to 40 mm, this tool series covers common suspension fork stanchion diameters used on mountain bikes, gravel suspension forks, e-bikes, and performance MTB forks. The long M6 threaded rod design allows the tool to apply controlled pressure from both sides, helping the seal enter the fork lower leg straight and evenly.

Each press tool uses a size-marked blue press head for easy identification. The tool also features a quick-release nut design and built-in flat bearing for smoother operation. Optional wall-mounted storage racks are available for organizing the full tool set in professional workshops or home bike repair areas.

Key Features

• Professional Fork Seal Installation Tool
  Designed for pressing bicycle suspension fork dust seals and oil seals into place.
• Multiple Size Options
  Available in 30 / 32 / 34 / 35 / 36 / 37 / 38 / 40 mm to fit different fork stanchion sizes.
• Even and Stable Pressing Force
  Helps keep the tool parallel to the fork lower leg for stable and balanced force distribution.
• Long M6 Threaded Rod Design
  Allows controlled installation from both ends of the fork lower leg.
• Quick Release Nut Design
  Makes tool setup and removal faster during maintenance work.
• Built-in Flat Bearing
  Reduces friction and helps the tool rotate smoothly while pressing the seal.
• Size-Marked Press Head
  Each tool head is clearly marked with its size for quick identification.
• Polymer 3D Printed Parts
  Some blue parts are made using high-polymer 3D printing technology. Visible layer lines or seam textures are normal and do not affect use.
• Wall Storage Rack Available
  RL340 and RL341 racks keep the press tools organized and easy to access.

Important Notes

• Please confirm your suspension fork stanchion diameter before purchase.
• The front fork lower leg holes on both damper side and air side should be ≥ 6 mm, otherwise the M6 threaded rod may not pass through.
• Install clockwise according to the product design.
• Keep the press head parallel to the fork lower leg during installation for even force.
• Some polymer parts are made by 3D printing. Layer lines and seam textures are normal manufacturing marks and do not affect use.
• Manual measurement may have slight tolerance.
