Product Overview
This high-performance diaphragm and cup seal is professionally engineered for Atlas Copco TEX75 handheld hydraulic rock drill, the core model of TEX series hydraulic breaking equipment widely deployed in mining, municipal demolition and road construction hydraulic systems. The product includes accumulator diaphragm and hydraulic piston cup seal, fully supporting overhaul and routine maintenance of TEX75 rock drill.
Adopting fabric-reinforced NBR nitrile rubber and wear-resistant PU polyurethane as core materials, this diaphragm & cup seal delivers outstanding nitrogen resistance, extreme impact resistance, wear resistance and anti-aging performance. It serves as a reliable direct replacement for original Atlas Copco sealing spare parts. The product effectively resolves common malfunctions including accumulator air leakage, cylinder internal leakage and system pressure attenuation, and significantly extends the service life of TEX75 drill under long-duration high-frequency impact, severe vibration and dusty harsh working conditions.

Key Selling Points
1. 100% Exact OEM Replacement
Fully compatible with original Atlas Copco TEX75 hydraulic rock drill and precisely matched with standard OEM dimensions and part numbers. No cutting, grinding or extra modification is required. It enables quick direct installation for daily maintenance, field overhaul and emergency on-site repair, effectively cutting down equipment downtime and labor costs.
2. High-Grade Composite Sealing Materials
Core diaphragm adopts fabric-reinforced NBR with high tear resistance and elastic recovery, capable of tens of thousands of cyclic impact without cracking; hydraulic cup seal uses high-hardness PU material with strong anti-extrusion and wear resistance. The materials feature strong resistance to nitrogen aging, hydraulic oil corrosion and fatigue deformation. It maintains stable and reliable sealing performance continuously within the temperature range of -40°C to 120°C, adapting to alpine low-temperature mining and high-temperature underground construction environments.
3. Superior High Pressure & Anti-Impact Performance
The diaphragm and cup seal have passed strict 25MPa high-pressure and long-cycle impact simulation tests. It thoroughly eliminates accumulator nitrogen leakage and cylinder internal oil leakage, stabilizes hydraulic impact pressure, and ensures consistent striking force of TEX75 drill under heavy-load rock breaking, impact and high-vibration working conditions.
4. Targeted Specialized Component Design
Independently developed for TEX75 accumulator and piston sealing position, the curved bowl-shaped structure fits the inner cavity perfectly. Single independent packaging simplifies spare parts inventory sorting, shortens the overall repair cycle and reduces daily operation and maintenance costs of equipment.
5. Rigorous Factory Quality Inspection
Every diaphragm and cup seal undergoes air tightness test, high-pressure durability test and cyclic impact aging test before delivery. All products comply with original factory technical standards, providing long-term stable operation guarantee for mining and construction hydraulic equipment.
6. Extensive Application Scope
Specially designed for Atlas Copco TEX75 hydraulic rock drill, widely used on various heavy-duty engineering and mining equipment:
• Mining industry: Underground roadway tunneling, ore rock drilling, stone quarry mining
• Municipal demolition: Concrete road breaking, old building dismantling, pipeline foundation excavation
• Road & bridge engineering: Mountain rock excavation, tunnel construction, roadbed hard rock crushing
• Water conservancy project: Hydropower tunnel rock drilling, dam foundation trimming
• Emergency rescue engineering: Rock splitting, frozen soil breaking, slope reinforcement drilling
