Kit Components & Functions
| Component | Function |
|---|---|
| 1. Ultra-High-Pressure Piston Seal | Kevlar®-reinforced AU resists rock particle abrasion in 45 MPa mining cylinders. |
| 2. Quad-Lip Rod Seal | Four sealing layers prevent leakage in high-vibration drilling rigs. |
| 3. Rock-Dust Wiper System | Multi-stage scraper with carbide blades removes hardened silica deposits. |
| 4. Heavy-Load Guide Rings | Carbon-fiber PTFE handles 20+ ton side loads in excavator arm pivots. |
| 5. Chemical-Resistant O-Rings | FFKM seals withstand hydraulic fluids with acidic additives (pH 3–12). |
| 6. Anti-Extrusion Collars Seal | Titanium-reinforced collars prevent seal deformation under impact loads. |
Key Features & Benefits
✅ Mining-Grade Durability: 3x longer lifespan than standard seals in rock-crushing applications.
✅ Acid/Chemical Resistance: FFKM static seals compatible with phosphate-ester and water-glycol fluids.
✅ Precision Engineering: CNC-machined to match CAT 374F and Komatsu PC4000 OEM specifications.
✅ Containment System: Wiper traps 98% of abrasive particles, reducing cylinder wear by 70%.
