86334166 Flange for Montabert HC50 Hydraulic Drifter

The 86334166 Flange is a critical hydraulic connecting and fixing flange component specially engineered for Montabert HC50 hydraulic drifter. It acts as an intermediate mounting bridge between the main valve block, distribution plate and percussion cylinder assembly. It integrates high-pressure oil inlet/outlet threaded ports, multi-position bolt fixing holes and central positioning sealing bore, delivering stable hydraulic oil circulation and rigid locking of core drifter internal components.

Manufactured fully to Montabert OEM drawing standards with high-strength forged alloy steel, this flange provides direct plug-and-play interchangeability with original factory spare parts. In harsh underground mine, tunneling and quarry environments with continuous heavy percussion, high hydraulic pressure, abrasive rock dust and muddy corrosive water, it maintains perfect sealing of hydraulic circuits, eliminates oil leakage and loose assembly failure, minimizing unexpected downtime of your Montabert HC50 rock drill.
