234-2595 Seal Kit Components & Functions
| 1. Shock-Absorbing Piston Seal | Steel-reinforced TPE resists 50 MPa impact loads in breaker hammer systems. |
| 2. Quadruple-Lip Rod Seal | Four sealing barriers prevent leaks in crane boom cylinders under side loads. |
| 3. Impact-Resistant Wiper Seal | Tungsten-carbide scraper removes concrete debris during demolition operations. |
| 4. Low-Friction Guide Rings | MoS2-PTFE coating reduces breakaway force in sub-zero crane operations. |
| 5. High-Temp O-Rings | FVMQ material maintains flexibility in +140°C hydraulic systems. |
| 6. Pressure-Diffuser Backup Seal | Titanium-alloy rings distribute shock loads to protect primary seals. |
