Hoc accumulatōrium robustum diaphragma seal cup kit is specially developed for OKADA UB11-2 hydraulic rock breakers, widely matched on 6–9 ton small excavators and engineering demolition machinery. The full set includes main diaphragm seal cup, Anuli O , gaskets, dust seals and auxiliary sealing backup rings for complete breaker accumulator overhaul.
Constructus ex composito caoutchouc HNBR alto-performans importato cum strato fibroso renfortato, hic kit praebet excellentem resistentiam ad oleum, anti-fatigam, altam pressionem et adaptabilitatem ad temperaturas latas. Perfecte substituit partes diafragmatis originalis OKADA, efficaciter solvendo defectus communes ut fuga aeris accumulatoris, attenuatio pressionis, vis fracturae debilis et rupturae frequens diafragmatis, multum extendens vitam servitii continuum sub conditionibus operis gravium onerum et impactuum altae frequentiae.

Perfectly dimensioned to match original OKADA UB11-2 breaker accumulator structure; fully compatible with OEM part numbers OKADA-UB11-2 and DIA-UB112-001. No cutting, grinding, or modification required — direct plug-and-play installation.
Core diaphragm made of thickened fiber-reinforced HNBR composite material, offering superior resistance to hydraulic oil corrosion, impact fatigue, and aging. Maintains stable elastic sealing performance from −30°C to 120°C, preventing premature cracking under prolonged high-frequency impact.
All sealing components undergo rigorous 18 MPa high-pressure nitrogen tightness testing. Effectively prevent internal and external air leakage from accumulator, lock in stable nitrogen pressure, ensure consistent breaker impact frequency and breaking force, and eliminate weak-hammer failure.
Integrates all sealing accessories required for full accumulator maintenance of UB11-2 breaker. One set covers all wearing sealing parts, reduces repeated purchasing, shortens on-site repair downtime and lowers equipment operation maintenance cost.
Each diaphragm sigillum Kit undergoes air tightness, cyclic impact fatigue and high-low temperature aging tests before delivery, fully meets OEM production standards, delivers stable and reliable long-term construction performance.
Suitable for OKADA UB11-2 hydraulic breakers installed on various light & medium construction equipment: • 6–9 ton mini excavators (Kubota KX163, Sany SY75, XCMG XE75, Lovol FR75, Liugong 906E) • Small backhoe loaders • Road demolition & municipal engineering machinery • Quarry stone crushing equipment • Hydraulic hammer nitrogen accumulator energy storage system • Mobile heavy-duty impact construction machinery
