This heavy-duty accumulator diaphragm & seal cup is custom developed for Furukawa HB50G, F50, F70 hydraulic rock breakers. It serves as the core nitrogen sealing component of the breaker accumulator, effectively isolating hydraulic oil and nitrogen gas. Constructed with imported reinforced FKM fluororubber and high-toughness NBR composite material, the product boasts outstanding oil resistance, high temperature resistance, anti-tear and anti-aging performance. It thoroughly solves common failures including nitrogen leakage, insufficient striking force and weak hammer impact, greatly extending continuous service life of breakers under heavy mining & construction workloads.

Precisely matched to Furukawa HB50G, F50, F70 breaker accumulator structure, fully consistent with OEM part numbers KF70-10106, KHB50G-10107, KF5-10201. No cutting, grinding or modification required for direct installation, perfect fit without gaps.
Core diaphragm and seal cup adopt high-performance FKM + reinforced NBR composite formula. Enhanced anti-tear fiber layer inside the rubber body, excellent resistance to hydraulic oil erosion, high temperature aging and frequent pressure impact, stable performance under -40°C ~ 120°C severe working conditions.
All finished products pass 26MPa high-pressure air tightness fatigue test. Effectively prevent nitrogen loss and hydraulic oil permeation inside accumulator, maintain constant energy storage pressure, avoid the problem of striking force attenuation, keep consistent hammer impact power during long-time continuous operation.
Contains all matching sealing accessories required for full accumulator overhaul, one-stop complete spare parts. Reduce separate part procurement time, shorten on-site breaker maintenance downtime and lower overall equipment operation cost.
Each batch of diaphragms and seal cups undergoes air tightness cycling test, high temperature aging test and repeated impact fatigue test before delivery, fully meets OEM production standards, stable and reliable long-term heavy industrial use performance.
Specially matched for Furukawa HB50G/F50/F70 large hydraulic breakers, widely applied on heavy-duty construction equipment: • Large tonnage excavator mounted rock breakers • Open-pit mining crushing & mining machinery • Highway & municipal road demolition equipment • Quarry stone crushing production lines • Concrete structure demolition engineering vehicles • Heavy-duty mobile hydraulic breaking equipment
