Assessing Hydraulic Oil Seals: Key Factors and Performance Evaluation
Read More >
Discover how hydraulic seal kits work, their critical components, and why Guangzhou Jiarui Oil Seal Co., Ltd’s kits outperform standard solutions. Boost equipment uptime today.
Hydraulic systems lose 25% of efficiency due to seal failures (Fluid Power Journal). At Guangzhou Jiarui Oil Seal Co., Ltd, we engineer hydraulic seal repair kits that restore 98%+ of original equipment performance. This guide explains what hydraulic seal kits are, why they matter, and how to choose the right solution for your machinery.
A hydraulic seal kit is a precision-engineered set of components designed to repair or maintain hydraulic systems by:
✔ Preventing fluid leakage under extreme pressure (up to 50 MPa)
✔ Eliminating contamination ingress
✔ Reducing friction-induced wear
Key Industries We Serve:
Construction machinery(Excavators, Loaders, Bulldozer, Crane, Crushing Hammer etc)
Explore Our Hydraulic Seal Kits
| Component | Function | Jiarui Innovation |
| Piston Seals | Seal high-pressure fluid in cylinder chambers | PTFE-coated for 200°C thermal stability |
| Rod Seals | Prevent leaks along piston rods | Triple-lip design reduces wear by 40% |
| Wipers/Scrapers | Remove contaminants from rods | Military-grade polyurethane material |
| O-Rings | Static sealing between components | HNBR compound resists oil degradation |
| Backup Rings | Prevent seal extrusion under pressure | Fiber-reinforced thermoplastic design |
| Lab-Verified Performance: Our kits withstand 5 million pressure cycles (ISO 10766-1 certified). | ||
Warning Signs:
Fluid Leaks: Puddles under equipment or drops in hydraulic pressure
Reduced Efficiency: Slower cylinder movement or overheating
Contamination: Visible particles in hydraulic fluid (NAS 1638 > Class 8)
Pro Tip: Preventive maintenance with Jiarui kits extends seal life by 3x compared to emergency repairs.
Match OEM Specifications
Compare groove dimensions (ISO 5597/ISO 6547 standards)
Verify pressure ratings (10/20/35/50 MPa tiers)
Evaluate Material Compatibility
Hydraulic fluid type (mineral oil, HFD, biodegradable)
Temperature range (-50°C to 200°C options available)
Assess Environmental Factors
Abrasive conditions → Add multi-stage wipers
High vibration → Spring-energized seals
