Description

In HC20 Hydraulic Rock Drill (or Hydraulic Drifter) systems, the Seals kit 86684073 is a “critical hydraulic barrier”—it includes all tailored seals for core components (cylinder, valve, piston), working together to lock in high-pressure oil (up to 1800 psi) and block mining debris.

Montabert’s 800-hour replacement cycle is based on real-world wear: after 800 hours, even quality seals lose elasticity (from oil and vibration), causing 4-6 liters of monthly oil waste. Generic seal kits fail faster—low-grade rubber hardens in 500-600 hours, leading to leaks that damage expensive internal parts.

This Seals kit 86684073, as genuine OEM, solves these issues:

Durability: Special nitrile rubber (with anti-aging additives) retains flexibility for the full 800-hour cycle.
Perfect fit: Each seal’s size (tolerance ±0.003mm) matches HC20’s components exactly—no on-site modifications.
Protection: Blocks dust and oil leaks, extending the drill’s service life.

With short delivery (no 2-3 week waits) and good pricing, it’s ideal for mines needing reliable sealing—keeping HC20 efficient through every 800-hour cycle.
