This heavy-duty diaphragm & seal cup repair kit is specially designed for FURUKAWA HD612 hydraulic rock drifters, widely applied in underground mining, tunnel excavation and rock engineering construction. The full set includes accumulator diaphragm, hydraulic seal cups, O-rings, gaskets, backup rings and all matching sealing spare parts for complete drifter overhaul.
Manufactured with imported high-performance FKM fluororubber and reinforced fabric composite diaphragm material, the kit delivers outstanding hydraulic oil resistance, anti-fatigue, high-pressure shock resistance and wide temperature adaptability. It perfectly replaces original FURUKAWA OEM sealing parts, solves common failures such as diaphragm rupture, internal hydraulic leakage, impact power attenuation and accumulator pressure loss, effectively extending the service life of HD612 rock drill under long-time high-frequency impact working conditions.

Fully matched with original FURUKAWA HD612 rock drill, consistent with OEM part numbers HD612-07006 and HD612-90001. No cutting, modification or adjustment required for quick on-site installation, fully compatible with HD612 and HD612R versions.
Core diaphragm adopts multi-layer fabric composite FKM rubber, effectively resist repeated high-frequency pressure impact; auxiliary sealing parts use high-density imported fluororubber, anti-aging, anti-hydraulic oil corrosion, stable performance under -30°C to 120°C extreme working temperature.
All components pass 28MPa long-cycle fatigue impact testing. Solve core pain points of original parts: diaphragm cracking, seal cup deformation, internal oil leakage and accumulator pressure drop, maintain stable impact energy and consistent drilling efficiency of the rock drill.
Covers all diaphragm and sealing consumables needed for full machine maintenance of HD612 drifter. Integrated complete spare parts reduce separate purchasing steps, shorten on-site repair downtime and lower overall equipment operation and maintenance cost.
Every set undergoes air tightness test, high-pressure fatigue test and thermal aging test before delivery, fully meets FURUKAWA OEM production standards, guarantees stable and reliable long-term performance under heavy mining and tunneling loads.
Suitable for all construction and mining equipment equipped with FURUKAWA HD612 hydraulic rock drifter: • Underground metal mine tunneling drilling rigs • Coal mine roadway excavation jumbo drills • Highway/railway tunnel boring equipment • Hydraulic rock bolting drilling machines • Open-pit mine rock drilling vehicles • Heavy-duty mobile hydraulic drilling rigs • Underground closed-loop hydraulic impact systems
