1. 100% Exact OEM Replacement. Fully compatible with original Montabert BRP140-LOW / BRP145 / BRP150-LOW hydraulic breakers. Matches OEM part numbers 86633997, 86634011 and BKB-178-050. Zero modification required for direct installation, consistent assembly size with factory standard.
2. Premium Reinforced Sealing Material. Core diaphragm and seal cup adopt high-performance HNBR composite rubber with internal fiber reinforcement layer. Anti-nitrogen aging, anti-hydraulic oil corrosion and anti-repeated impact fatigue, stable operation under -35°C ~ 130°C complex working environment.
3. Zero Nitrogen Leakage & Stable Impact Output. All components pass 32MPa high-pressure nitrogen fatigue cycling test. Effectively eliminate accumulator air leakage, maintain stable nitrogen pressure, recover full impact energy and avoid breaker slow strike, weak breaking force and intermittent jitter.
4. Complete All-in-One Overhaul Kit. Contains all diaphragm, seal cup and auxiliary sealing accessories required for accumulator full maintenance. Integrated matching parts reduce spare parts matching time and cut equipment maintenance downtime & operating cost.
5. Strict Factory Quality Control. Every diaphragm seal kit undergoes air tightness, high-pressure nitrogen aging and repeated impact fatigue tests before delivery. Fully complies with Montabert OEM dimensional and performance standards, guaranteeing long-term stable construction performance.
6. Wide Application Scope. Suitable for Montabert BRP series hydraulic breakers installed on multiple heavy-duty engineering equipment:
• Medium & Large Excavators • Mining Rock Crushing Equipment • Road Demolition Machinery • Quarry Stone Breaking Hammers • Municipal Renovation Breakers • Construction Site Heavy Crushing Equipment • Mobile Hydraulic Rock Breaking Equipment
