Kinton Seals is trusted by professionals worldwide for providing high-quality seal kits for excavators, dozers, loaders, and other heavy machinery, ensuring reliable performance and long-lasting durability.
The SDLG excavator O-ring kit is designed to provide a complete sealing solution for critical hydraulic components. Each kit includes a wide range of durable O-rings that ensure tight sealing in distributor valves, hydraulic pumps, and hose connectors. By combining multiple specifications in one box, this kit helps operators and service teams perform quick replacements on-site, reducing downtime and keeping machines running efficiently.
Key Features and Benefits
- Complete Set in One Box – Includes multiple O-ring sizes commonly used in SDLG excavators. No need to source individual seals.
- Premium Material – Manufactured from high-quality NBR (Nitrile Butadiene Rubber) with excellent oil resistance, abrasion resistance, and long-lasting durability.
- Reliable Sealing Performance – Effectively prevents hydraulic fluid leakage, maintaining stable system pressure and ensuring safe operation.
- Wide Application Range – Specially designed for sealing needs in distributor valves, hydraulic pumps, and hose connectors.
- Convenient Maintenance – Organized in a well-labeled box, making it easy for mechanics and operators to find the right seal during service.
Material and Manufacturing Process
The seals are made from NBR90° material, engineered for heavy-duty excavator use. This compound provides:
- Strong resistance to hydraulic oil, diesel, and lubricants.
- Excellent elasticity and sealing recovery.
- Stable performance across a wide temperature range.
- Reduced wear and longer replacement intervals compared to ordinary rubber seals.
Precision Material Weighing
Each raw material, including polyurethane, PTFE, and rubber compounds, is accurately weighed according to strict formulation standards. This ensures consistent chemical properties, balanced elasticity, and reliable performance across every seal.
Mold Preparation & Material Placement
High-precision molds are thoroughly cleaned and preheated before material placement. The prepared compound is carefully filled into the mold cavities to avoid defects such as bubbles or uneven density, ensuring flawless shaping of the seals.
High-Pressure Compression Molding
Using advanced compression molding machines, the materials are subjected to high temperature and pressure. This process guarantees excellent dimensional accuracy, uniform density, and the proper hardness required to withstand hydraulic pressure and harsh jobsite conditions.
Rigorous Quality Inspection
Every finished seal undergoes strict inspection procedures, including dimensional checks, surface finish evaluation, and sealing performance tests. Only seals that meet international OEM standards are packaged and delivered, ensuring reliable operation for your machine.
This meticulous process ensures that every seal kit meets or exceeds OEM standards.
Application Areas
This O-ring kit is particularly suitable for key hydraulic parts of SDLG excavators:
- Distributor Valve – Ensures accurate control of hydraulic flow and prevents leakage under high pressure.
- Hydraulic Pump – Maintains stable pump operation, extending service life and preventing costly breakdowns.
- Hose Connectors – Provides secure sealing at connection points to avoid oil seepage and system contamination.
Why Choose This O-Ring Kit for SDLG Excavators?
- OEM-Compatible Fitment – Designed to match SDLG hydraulic system standards.
- Cost-Effective Solution – A single kit eliminates the need to purchase seals separately.
- Reduced Downtime – Fast replacement reduces machine idle time.
- Trusted Quality – Manufactured under strict quality control to meet or exceed industry standards.
Packaging and Storage
Each O-ring kit comes in a durable plastic case with individual compartments for each size. Clear labeling ensures quick identification and easy use during maintenance. The compact design makes it convenient for both workshop storage and field repairs.
Maintenance Tips
- Store the kit in a cool, dry environment to maintain rubber elasticity.
- Replace O-rings at regular maintenance intervals or whenever leakage is detected.
- Keep the kit sealed when not in use to prevent contamination by dust or oil.
- Always clean the sealing surface before installation to ensure proper fit and performance.
