Why this replacement matters

  • Restores seal performance -> BS4518 5.1x1.6 O-ring dimensions match the old seal -> tool returns to service
  • Speeds routine service -> compact O-ring can be swapped during strip-down -> crews avoid a return visit
  • Reduces leak risk -> nitrile rubber compresses to form a small seal -> protects uptime after maintenance

Product Details

This nitrile sealing ring replaces a worn or damaged small seal in compatible Husqvarna cutting and drilling equipment. It suits maintenance teams and owner-operators keeping K 2500, K 3600, DM 280 and DM 340 units serviceable between jobs, helping prevent leaks and downtime from a failed seal.

  • Restore sealing performance during routine saw or core drill servicing.
  • Reduce avoidable downtime by replacing small wear parts before failure.
  • Fit OEM-spec maintenance work on selected Husqvarna and Partner machines.
  • Keep service kits stocked for quick repairs on active jobsites.

Check the machine parts diagram before fitting, as this 5.1 x 1.6 nitrile O-ring only suits specific seal positions.
