Integrated sealing at the liner bolt hole and thread
The Kombo Washer combines a washer and nut in an interconnected assembly for mill liner bolt sealing. A non-stick elastomer with conical rings seals the bolt hole and thread to address slurry fines migrating along the thread. The assembly includes an all-steel prevailing-torque lock-nut.
The Kombo Washer is Australian designed and owned, and precision-manufactured in Germany by Flaig + Hommel. Metric and imperial sizes are available to suit mill liner bolt specifications. The compressing elastomer is designed to seal imperfect holes and uneven mill surfaces, while the one-piece configuration brings the sealing and fastening components together.
