Product Overview
This high-performance diaphragm and cup seal is professionally engineered for Atlas Copco TEX250 handheld hydraulic rock drill, the heavy-duty flagship model of TEX series hydraulic breaking equipment widely deployed in mining, large-scale municipal demolition, tunnel and road construction hydraulic systems. The product includes accumulator diaphragm and hydraulic piston cup seal, fully supporting complete overhaul and routine maintenance of TEX250 rock drill.
Adopting fabric-reinforced NBR nitrile rubber and wear-resistant PU polyurethane as core materials, this diaphragm & cup seal delivers outstanding nitrogen resistance, ultra-heavy 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 TEX250 drill under long-duration super high-frequency impact, intense vibration and heavy-dust harsh working conditions.

Key Selling Points
1. 100% Exact OEM Replacement
Fully compatible with original Atlas Copco TEX250 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 thickened fabric-reinforced NBR with ultra-high tear resistance and stable elastic recovery, capable of hundreds of thousands of heavy cyclic impact without cracking; hydraulic cup seal uses high-hardness wear-resistant PU material with strong anti-extrusion and anti-scuff performance. 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 tunnel construction environments.
3. Superior High Pressure & Anti-Impact Performance
The diaphragm and cup seal have passed strict 28MPa high-pressure and long-cycle heavy impact simulation tests. It thoroughly eliminates accumulator nitrogen leakage and cylinder internal oil leakage, stabilizes hydraulic impact pressure, and ensures consistent powerful striking force of TEX250 drill under super heavy-load rock breaking, continuous impact and high-vibration working conditions.
4. Targeted Specialized Component Design
Independently developed for TEX250 large-size accumulator and piston sealing position, the thickened 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 heavy-duty impact 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 large mining and heavy engineering hydraulic equipment.
6. Extensive Application Scope
Specially designed for Atlas Copco TEX250 heavy hydraulic rock drill, widely used on various heavy-duty engineering and mining equipment:
• Mining industry: Large open-pit mining, underground tunnel tunneling, hard ore rock drilling, stone quarry massive rock breaking
