This heavy-duty accumulator diaphragm (rubber seal cup) is professionally engineered for FURUKAWA HB3G, HB5G and F2 hydraulic rock breakers. It serves as the core gas-hydraulic separation component of the breaker accumulator, effectively isolating nitrogen and hydraulic oil.
Manufactured with imported high-performance HNBR and FKM fluororubber composite material, the diaphragm boasts outstanding oil resistance, high-frequency fatigue resistance, low-temperature flexibility and anti-aging performance. It perfectly matches original FURUKAWA OEM standards, solves common failures such as nitrogen leakage, striking force attenuation and abnormal breaker vibration, and greatly extends the service life of hydraulic hammers under long-term mining & construction heavy-load impact conditions.系列隔膜

Fully dimensionally consistent with original FURUKAWA HB3G/HB5G/F2 breaker diaphragms, matches OEM part numbers 10642, FXJ275, 9200612. No cutting, grinding or modification required for direct replacement installation.
Core diaphragm adopts HNBR-FKM dual-layer composite rubber with fiber reinforcement. It resists hydraulic oil corrosion, high-frequency impact fatigue and ozone aging, maintaining stable elasticity within -30°C to 115°C wide temperature range.
All finished diaphragms pass strict 36MPa high-pressure air tightness and repeated fatigue impact tests. It eliminates nitrogen leakage and oil cross-mixing failures, keeps consistent accumulator energy storage capacity and stable breaker striking force without power drop during continuous operation.
Comes with supporting O-ring gaskets required for accumulator overhaul in one set. Complete matching parts simplify on-site maintenance, shorten equipment downtime and reduce overall machinery operation and repair costs.
Every diaphragm undergoes air tightness, high-frequency impact fatigue and thermal aging testing before delivery. Production complies with OEM quality standards, ensuring stable long-term reliability in harsh construction and mining environments.
Suitable for FURUKAWA HB3G/HB5G/F2 hydraulic breakers mounted on multi-scene heavy-duty equipment:
