For HC50 Hydraulic Rock Drill (or Hydraulic Drifter) maintenance in mining, the O_ring 86363595 is a make-or-break sealing part. Over a decade in mining equipment, I’ve seen generic O_rings fail repeatedly: their cheap rubber cracks under HC50’s 1500+ psi pressure, causing hydraulic leaks that waste oil, contaminate work zones, and cut drilling speed by 20-30%. Worse, leaks damage costly cylinders—leading to $4,000+ in repairs and days of downtime.
This O_ring 86363595 avoids all that, as a genuine OEM part built to Montabert’s standards. Its rubber resists high pressure, mineral hydraulic oils, and mine dust—three top seal killers. It fits HC50’s sealing grooves perfectly, no forced installation needed.
