This premium full overhaul diaphragm & seal repair kit is specially engineered for INGERSOLLAND YH45 hydraulic rock drill, widely applied in underground mining, tunneling and rock excavation construction machinery. It contains complete accumulator diaphragm rubber cup, shaft seals, O-rings, gaskets, PTFE backup rings and all matching sealing consumables for full machine maintenance.
Made of imported high wear-resistant PU composite + FKM fluororubber, the kit features outstanding fatigue resistance, hydraulic oil resistance, pressure impact resistance and low temperature flexibility. It perfectly replaces original Ingersoll Rand OEM diaphragm & sealing parts, solves common failures including accumulator leakage, pressure attenuation, weak impact force and frequent diaphragm rupture, greatly extending the continuous service life of YH45 rock drill under heavy rock drilling working conditions.

Fully dimensional consistent with original INGERSOLLAND YH45 rock drill spare parts, matches OEM part numbers IR-YH45-DIAP, 3115192645 and 90516801. No cutting, grinding or modification required for quick on-site installation, perfectly fit accumulator cavity and each sealing mating surface.
Core energy storage diaphragm cup adopts reinforced PU composite material with anti-fatigue treatment; auxiliary sealing components use high-performance FKM fluororubber with PTFE backup rings. Resists hydraulic oil corrosion, frequent pressure impact and low-temperature hardening, stable operation under -30°C ~ 120°C wide temperature range.
All parts pass 28MPa long-cycle pressure fatigue test, effectively eliminate accumulator internal leakage, external oil seepage and diaphragm early cracking failures. Maintain stable impact energy and constant drilling power during continuous rock drilling, reduce pressure loss and improve drilling efficiency.
Covers all diaphragm, rubber cup and sealing parts required for full YH45 rock drill overhaul. One set meets full machine maintenance demand, avoids separate purchasing scattered spare parts, shortens equipment downtime and lowers overall mining operation maintenance cost.
Every seal kit undergoes air tightness test, high-pressure fatigue test and aging resistance test before delivery, fully meets Ingersoll Rand OEM manufacturing standards. Stable quality for long-term heavy-duty mining and tunnel construction working conditions.
Suitable for all equipment equipped with INGERSOLLAND YH45 hydraulic rock drill: • Underground metal mine tunneling & blasting drilling rigs • Coal mine roadway bolting drilling equipment • Hydraulic crawler drilling jumbos for highway tunnel engineering • Quarry rock excavation drill rigs • Hydraulic rock drilling auxiliary power units • Underground non-excavation horizontal directional drilling machinery • Heavy-duty mobile rock breaking & drilling equipment
