Product Overview

This heavy-duty accumulator diaphragm & seal cup repair kit is customized for DAEMO B140-10 hydraulic rock breakers, widely matched on medium-sized excavators for mining, demolition and road construction. It includes core accumulator diaphragm, oil seal cups, O-rings, dust seals, gaskets and PTFE backup rings for full breaker overhaul maintenance.

Constructed with imported high-strength FKM fluororubber and wear-resistant PU composite material, the kit boasts outstanding shock resistance, oil resistance, low temperature resistance and anti-fatigue performance. It perfectly replaces original DAEMO spare parts, solves common faults such as nitrogen leakage, internal oil seepage, impact power attenuation and diaphragm rupture, greatly extending the service life of the hydraulic breaker under continuous high-frequency impact working conditions.
