This heavy-duty diaphragm & seal repair kit is customized for MONTABERT V1600 hydraulic rock drill / hydraulic breaker, widely applied in mining, tunnel excavation, quarry and municipal rock breaking machinery. It contains complete accumulator rubber diaphragm (leather cup), shaft oil seals, O-rings, gaskets, PU backup rings and all overhaul sealing spare parts for full machine maintenance.
Adopted imported high-toughness FKM fluororubber and wear-resistant NBR composite material, the kit features outstanding hydraulic oil resistance, high-low temperature resistance, anti-fatigue and anti-impact performance. It perfectly replaces original MONTABERT OEM sealing parts, thoroughly solves common failures including diaphragm rupture, nitrogen leakage, hydraulic oil seepage, pressure attenuation and weak impact force, effectively extending the service life of V1600 rock drill under continuous heavy impact working conditions.

Fully compatible with original MONTABERT V1600 hydraulic rock drill. Matches official OEM part numbers 86634664 full seal kit and 86633914 standard diaphragm membrane. No cutting, grinding or modification required, direct on-site installation to shorten repair downtime.
Core diaphragm leather cup adopts thickened FKM fluororubber raw material with anti-fatigue reinforced layer. It resists frequent high-frequency impact, hydraulic oil corrosion and high-temperature aging, stably working within -30°C to 120°C harsh construction environment, avoiding early diaphragm cracking and nitrogen leakage.
All sealing components pass strict 18MPa hydraulic pressure fatigue cycle test. Effectively stop internal nitrogen leakage and external hydraulic oil seepage, maintain stable accumulator pressure, guarantee consistent impact energy of the rock drill without power attenuation during long-time continuous operation.
Integrates all sealing spare parts required for full machine overhaul of V1600 drifter, including vulnerable diaphragm leather cup, all sizes O-rings, piston seals and anti-extrusion backup rings. One set covers all maintenance demands, reduces separate part procurement cost and shortens machine idle repair time.
Every complete seal kit undergoes air tightness test, high-pressure impact fatigue test and high-temperature aging test before delivery, fully meets MONTABERT OEM manufacturing standards, stable and reliable for long-term heavy-load mining and engineering operation.
Suitable for all equipment equipped with MONTABERT V1600 hydraulic rock drill / breaker: • Medium & large excavator mounted hydraulic breakers (20–30 ton excavator matching) • Open-pit mining rock blasting drilling rigs • Tunnel excavation & underground mine bolting drifters • Quarry stone crushing & demolition machinery • Municipal road renovation, rock foundation excavation equipment • Hydraulic nitrogen accumulator impact breaking systems
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.
