This heavy-duty accumulator diaphragm & cup repair kit is custom-developed for SOOSAN SB150, SBU+125, SBU+140 hydraulic rock breakers, widely matched to medium & large excavator hammer attachments for mining, demolition and road construction. The full set includes integrated accumulator diaphragm, rubber cup, complete O-rings, piston seals, rod seals, PTFE backup rings and cylinder gaskets for full breaker overhaul maintenance.
Constructed with imported reinforced HNBR and FKM fluororubber with fabric reinforcement, the kit delivers outstanding hydraulic oil resistance, ultra-high pressure fatigue resistance, low-temperature flexibility and anti-aging performance. It perfectly replaces original SOOSAN diaphragm and sealing components, solves common faults including accumulator air leakage, weak impact force, hydraulic oil seepage and pressure attenuation, and greatly extends breaker service life under continuous high-frequency impact heavy-duty operation.

Fully dimensionally matched with original SOOSAN SB150, SBU+125, SBU+140 breaker parts, consistent with OEM part numbers C71113, SOOSAN-SB150, SOOSAN-SBU125, SOOSAN-SBU140. No cutting, grinding or modification required for direct plug-and-play installation.
Core accumulator diaphragm adopts fabric-reinforced high-performance HNBR composite material; dynamic sealing parts use high-temperature resistant FKM fluororubber with PTFE anti-extrusion backup rings. Outstanding oil corrosion resistance, crack resistance and high-frequency fatigue resistance, stably operate in -35°C to 135°C extreme working environment.
All components pass strict 125MPa ultra-high pressure fatigue cycle testing. Effectively eliminates accumulator nitrogen leakage and cylinder internal/external oil seepage, maintains stable nitrogen pre-charge pressure and hydraulic driving pressure, ensures consistent breaker impact frequency and striking force without power drop.
Integrates all diaphragm, rubber cup and sealing consumables needed for full breaker disassembly maintenance. One kit covers accumulator and main cylinder two core sealing systems, reduces separate parts procurement time and cuts equipment downtime & maintenance cost.
Every set undergoes air tightness test, high-pressure burst test, alternating cold & hot aging test and repeated impact fatigue test before delivery, fully meets SOOSAN original equipment manufacturing standards, guarantees long-term stable reliability under harsh construction site conditions.
Suitable for SOOSAN SB150, SBU+125, SBU+140 hydraulic rock breakers mounted on various heavy-duty construction equipment:
Welcome to HOVOO, a Chinese seal factory. Production of PU, Rubber and PTFE seals. The seals include O-ring, piston seal, rod seal, Gray ring and gas seal.
