Fully dimensionally consistent with original Ingersoll Rand YH65 rock drill spare parts, matching OEM part numbers IR-YH65 and 2651206407. Zero modification required for quick on-site installation, perfectly fitting YH65 and YH65RP drifter variants.
The core accumulator diaphragm cup adopts thickened imported PU composite material, with enhanced anti-fatigue and anti-rupture performance. Supporting FKM rubber seals resist hydraulic oil corrosion and high-temperature aging, stable operation under -30°C to 120°C harsh working environment.
All components pass strict 28MPa high-pressure impact cycle testing. Effectively eliminate accumulator air leakage, internal hydraulic leakage and external oil seepage, maintain stable impact power and consistent drilling efficiency of the rock drill.
Covers all sealing and diaphragm consumables needed for full YH65 machine maintenance. Integrated complete accessories save parts matching time, shorten equipment downtime and reduce overall mining operation maintenance costs.
Every seal kit undergoes air tightness fatigue test, high-pressure impact test and high-low temperature aging test before delivery, fully meets Ingersoll Rand OEM production standards, delivering stable long-term performance under heavy mining loads.
Suitable for all construction & mining equipment equipped with Ingersoll Rand YH65 hydraulic rock drifter: • Underground mine tunneling drilling rigs • Tunnel excavation jumbo drill carts • Open-pit quarry rock drilling equipment • Hydraulic rock bolter machines • Mobile full hydraulic drilling rigs • Heavy-duty impact rock drilling hydraulic systems
