This heavy-duty accumulator cup and diaphragm is custom engineered for Furukawa HB10G & F12 hydraulic rock breakers. It acts as the core isolation component inside the nitrogen accumulator, separating high-pressure nitrogen chamber and hydraulic oil circuit.
Manufactured with imported modified HNBR and reinforced vulcanized rubber, the diaphragm features outstanding oil resistance, high-frequency fatigue resistance, anti-aging and anti-cracking performance. It perfectly replaces original Furukawa OEM diaphragm parts, solves common failures including nitrogen leakage, insufficient impact force, pressure attenuation and frequent overheating, and greatly extends breaker service life under long-term mining & demolition heavy-load operation.

Fully dimensional matching original Furukawa HB10G and F12 breaker accumulator cavity, corresponds to OEM part numbers KHB10G-10213 and KF12-10114. No cutting, polishing or modification required for direct plug-and-play installation.
Core diaphragm adopts high-performance modified HNBR composite rubber with internal fiber reinforcement layer. Excellent hydraulic oil corrosion resistance, low-temperature soft retention and high-temperature anti-hardening performance, stable elasticity maintained from -40°C to 130°C extreme working environment.
Strict cyclic high-frequency stretching test under 60MPa peak pressure, effectively isolate nitrogen and hydraulic oil. Eliminate internal air leakage, oil seepage and pressure loss, guarantee stable impact energy and consistent breaker hitting power during continuous operation.
Dome integrated molding structure, uniform stress distribution, avoid edge tear and local deformation under frequent reciprocating compression. Single part covers full accumulator sealing repair demand, simplify maintenance steps and reduce equipment downtime cost.
Every finished diaphragm passes air tightness, high-pressure fatigue, thermal aging and oil immersion tests before delivery, fully meets OEM technical standards, delivers stable long-term performance for heavy-duty construction sites.
Specially matched for Furukawa HB10G/F12 hydraulic breakers equipped on various heavy engineering machinery:
