This high-performance accumulator diaphragm & seal cup is professionally developed for Furukawa HB2G and F1 hydraulic rock breakers. It serves as the core energy storage sealing part of the breaker nitrogen accumulator, effectively isolating hydraulic oil and nitrogen to stabilize impact power.
Manufactured with imported high-strength HNBR and reinforced fiber composite material, it boasts outstanding impact resistance, oil resistance, high & low temperature resistance and anti-fatigue performance. It perfectly replaces original Furukawa OEM diaphragms, solves common failures such as nitrogen leakage, insufficient impact force and frequent pressure loss, and greatly extends the service life of breakers under long-cycle heavy impact operation.

Fully dimensional matching original Furukawa HB2G and F1 breaker accumulator chambers, corresponding to OEM part numbers KBF1-00105 and KHB2G-10203. No cutting, grinding or modification required for direct installation.
Adopts imported HNBR rubber with internal fiber reinforcement layer, effectively resisting hydraulic oil corrosion, high-frequency impact fatigue and thermal aging. Stable elastic performance maintained within -30°C to 125°C working environment.
All finished diaphragms pass 26MPa high-pressure air tightness and repeated impact fatigue tests. It completely avoids internal nitrogen leakage, maintains constant accumulator pressure, ensures continuous and stable breaking impact force, and eliminates weak hammer failure.
Equipped with matched positioning gaskets, dust O-rings and backing rings required for accumulator overhaul. One-stop complete parts reduce on-site maintenance time and lower equipment operation downtime cost.
Each diaphragm undergoes air tightness, high-pressure endurance and alternating impact aging tests before delivery, fully meeting Furukawa original manufacturing standards to guarantee long-term reliable construction performance.
Suitable for Furukawa HB2G / F1 hydraulic breakers matched with mini excavators in various heavy-duty construction scenarios:
