Operating Pressure: Up to 35 MPa (5,076 psi)
Temperature Range: -40°C to +120°C (-40°F to +248°F)
Seal Material: Nitrile Rubber (NBR) / Polyurethane (PU) blend for balanced flexibility and abrasion resistance
Hardness: 85 ± 5 Shore A (dynamic seals), 70 ± 5 Shore A (static seals)
Fluid Compatibility: Compatible with mineral-based hydraulic oils, synthetic fluids, and water-glycol solutions
Friction Coefficient: ≤ 0.25 (optimized for smooth cylinder movement)
Design Standards: Manufactured to ISO 9001 quality standards with precision tolerances
Safety First: Depressurize the hydraulic system completely and secure the equipment before disassembly.
Clean Workspace: Perform repairs in a clean, dust-free environment to prevent contamination.
Inspect Components: Check cylinder walls, piston rods, and grooves for wear or damage; replace if beyond service limits.
Proper Lubrication: Lightly coat all seals with clean hydraulic fluid during installation to prevent dry-start damage.
Correct Orientation: Ensure all seals (especially lip seals) are installed in the correct direction as indicated in the manual.
Avoid Sharp Tools: Use plastic or rubber tools to position seals and avoid cuts or nicks.
Pressure Testing: After reassembly, conduct a gradual pressure test and check for leaks before returning to full operation.
Q1: Which Komatsu excavator models use the 707-99-13410 hydraulic cylinder seal?
