Winner SK-10A-3 Seal Kit Technical Specifications
Material Composition and Fluid Compatibility
The Winner SK-10A-3 is a comprehensive replacement seal kit engineered specifically for maintaining and restoring the sealing integrity of 10-series industrial hydraulic cartridge valves. The kit comprises precision-molded components crafted from high-grade Buna-N (Nitrile) elastomer as standard, with optional Viton configurations available for high-temperature or aggressive fluid environments. These materials provide exceptional resistance to mineral-based hydraulic oils, petroleum products, and synthetic lubricants, preventing fluid bypass and maintaining operating pressure across wide temperature ranges.
Component Breakdown and Maintenance Integration
Designed for straightforward field or workshop servicing, the SK-10A-3 package includes all necessary internal O-rings, backup rings, and specialized seals required for a complete cartridge overhaul. Each element is manufactured to strict dimensional tolerances to ensure a perfect fit into standard 10-series valve cavities and body grooves, eliminating extrusion under high-pressure differential stress up to 350 bar. Utilizing this genuine seal kit ensures restored operational reliability, prevents external leakage, and extends the overall service life of heavy-duty hydraulic control assemblies.
