This heavy-duty accumulator diaphragm & seal cup repair kit is customized for TOYO TOP200 hydraulic rock breakers, widely matched with 20–30 ton excavators for demolition, mining and road construction. The full set includes accumulator diaphragm, oil seal cups, O-rings, gaskets and retaining back-up rings for complete breaker overhaul maintenance.
Crafted with imported high-performance PPDI composite rubber and reinforced fiber layer, the kit delivers outstanding high-temperature resistance, fatigue resistance and nitrogen gas tightness. It perfectly replaces original TOYO spare parts, solves common faults like nitrogen leakage, weak impact force and unstable hammer output, and greatly extends breaker service life under continuous heavy impact operation.

1. 100% Exact OEM Replacement. Fully dimensional compatible with original TOYO TOP200 hydraulic breakers. Matches OEM part numbers TOYO-TOP200 and 892002001. No cutting or modification required for direct plug-and-play installation.
2. Premium Imported Composite Diaphragm Material. Core accumulator diaphragm adopts high-elastic PPDI rubber with built-in fiber reinforcement. Anti-fatigue, anti-aging, gas and oil resistant, stable performance under -30°C to 150°C long-time high-frequency impact.
3. Zero Nitrogen Leakage & Stable Impact Power. All sealing components pass strict 18MPa nitrogen tightness cycling tests. Effectively stops internal and external gas/oil leakage, maintains constant accumulator pressure, restores full hammer impact energy and consistent breaking efficiency.
4. Complete All-in-One Overhaul Kit. Contains all diaphragm and sealing consumables needed for full breaker disassembly maintenance. Integrated full-set parts cut down repair downtime and reduce overall equipment operation maintenance costs.
5. Strict Factory Multi-Round Quality Inspection. Every diaphragm kit undergoes air tightness, high-pressure fatigue and high-temperature aging tests before shipment. Fully meets OEM production standards to guarantee stable long-term construction site performance.
6. Wide Application Scope. Matches TOYO TOP200 hydraulic breakers mounted on multiple heavy-duty engineering machines:
• 20–30 ton medium excavators (Sany 215/245, XCMG 210/240, Liugong 922, SDLG 225) • Medium backhoe loaders • Municipal demolition machinery • Quarry & mining crushing equipment • Road renovation & concrete breaking equipment • Heavy-duty mobile hydraulic breaking attachments
