Description

In HC20 Hydraulic Rock Drill (or Hydraulic Drifter) systems, the Seals kit 86686755 is a “hydraulic system protector”—it includes all seals needed for key components, ensuring no oil leaks or debris intrusion. Montabert’s 800-hour cycle comes from data: after 800 hours, seals lose elasticity (due to oil and vibration), causing 4-6 liters of monthly oil waste.

From mining maintenance, generic kits fail fast—low-quality rubber hardens in 500-600 hours, leading to leaks and component damage.
This Seals kit 86686755, as genuine OEM, meets strict standards:
  1. Durability: Special nitrile rubber (anti-aging) retains elasticity for 800+ hours.
  2. Full compatibility: Exact matches HC20’s cylinder, valve, and piston—no fit issues.
  3. Protection: Blocks dust, extending internal component life.
With short delivery (no 2-3 week waits) and good pricing, it’s ideal for mines needing reliable sealing—keeping HC20 efficient for every 800-hour cycle.
