LZ011200 Seal Kit Components
| Component | Primary Function |
| Rod Seals | Seals the piston rod, preventing external fluid leakage and ensuring smooth movement. |
| Piston Seals | Creates a dynamic seal between the piston and cylinder bore, maintaining pressure differential. |
| Wiper Seals (Dust Seals) | Cleans the rod surface, preventing dirt and contaminants from entering the cylinder. |
| Wear Rings (Guide Bands) | Guides the piston and rod, preventing metal-to-metal contact and ensuring concentric movement. |
| Buffer Seals | Absorbs pressure spikes and protects the primary rod seal from high-pressure extrusion. |
| O-rings & Backups | Provides static and dynamic sealing for various internal connections and prevents seal extrusion under pressure. |
