Product Advantages
1. Original Genuine Parts, High-Pressure Heavy-Duty
Original Sany parts (60220997) compatible with high-pressure circuits of 36-ton excavators, withstands 380bar pressure, impact and fatigue resistant.
2. Four-Ply Steel Wire, Explosion-Proof and Durable
4SH braided structure, pulse life >400,000 cycles; outer rubber is oil and aging resistant, ensuring long service life in mining/heavy-duty conditions.
3. Thread + Flange Dual Sealing, Zero Leakage
Dual protection from DKOS threads and SFL flanges ensures reliable high-pressure sealing, avoiding risks of hose bursting and oil leakage.
4. Short-Length Customization, Compact Installation
Factory-standard short length of 400mm with 90° flange, suitable for narrow spaces, direct replacement without modification required.
Installation Compatibility Notes
- Compatible With: High-pressure interfaces of boom/dipper stick/main valve on SY365H/SY375H.
- Installation: Clean fittings/flange surfaces, replace O-rings with new ones; secure firmly to avoid bending radius <340mm.
- Pressure Testing: Maintain 38MPa pressure for 5 minutes; no leakage indicates pass.
