This heavy-duty diaphragm & cup seal repair kit is specially developed for MONTABERT V1800 hydraulic rock breakers, widely matched with 20–35 ton excavators for mining, quarrying and demolition construction works. It contains full set accumulator rubber diaphragms, hydraulic cup seals, O-rings, gaskets, PTFE backup rings and valve sealing parts for complete breaker overhaul maintenance.
Constructed with imported high-performance FKM fluororubber, reinforced NBR and fabric-reinforced rubber, the kit delivers outstanding nitrogen resistance, hydraulic oil resistance, anti-fatigue and anti-aging performance. It fully replaces original MONTABERT OEM sealing components, thoroughly solves common failures including accumulator nitrogen leakage, hydraulic internal/external oil seepage, insufficient striking power and unstable impact frequency, effectively extending the whole service life of V1800 hydraulic hammer under long-term heavy impact working conditions.

Fully dimensionally compatible with original MONTABERT V1800 series hydraulic breakers, matching official OEM part numbers MONTABERT-V1800, 10289565 and 86778792. Zero modification required for direct on-site installation, perfectly matching breaker accumulator and hydraulic cylinder sealing grooves.
Core diaphragm and cup seal parts adopt fabric-reinforced FKM composite rubber, with added PTFE anti-extrusion backup rings. The material resists nitrogen corrosion, hydraulic oil swelling, high-frequency impact fatigue, and maintains stable sealing performance under -30°C to 120°C wide temperature fluctuation.
All sealing components pass strict 16.5MPa high-pressure nitrogen and hydraulic cycling fatigue tests. Effectively eliminates accumulator nitrogen loss and cylinder oil leakage, stabilizes breaker dual-frequency striking output, avoids power drop caused by seal failure during continuous rock breaking.
Covers all diaphragm, cup seal and auxiliary sealing spare parts needed for full disassembly maintenance of V1800 hammer. Integrated full set parts reduce separate part procurement time, shorten on-site repair downtime and lower overall equipment operation maintenance cost.
Every full seal kit undergoes air tightness, high-pressure nitrogen aging and repeated impact fatigue testing before delivery, fully meets MONTABERT OEM production standards, guarantees long-term stable and reliable performance under harsh mining and construction working conditions.
Designed for MONTABERT V1800 / V1800 EVO hydraulic rock breakers installed on multiple heavy-duty engineering 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.
