The 6C9-LN/6D9-LN WSV right-angle over-plate coupling is a high-performance hydraulic connector designed for high-pressure fluid systems, compliant with international standards DIN 2353/ISO 8434.
Features
1. 24° Cone Seal on Both Ends Equipped with metric male threads and integrated 24° cone seals (per DIN 2353), ensuring reliable sealing under high pressure and superior leak-proof performance.
2. Compatible with Multiple Tube Standards
Light Series (24° Cone Light Connection): Supports tube sizes 06L-42L.
Heavy Series (24° Cone Heavy Connection): Supports tube sizes 06S-38S.
Accommodates diverse load requirements for various industrial applications.
3. Ultra-High Pressure Resistance
Operating pressure up to 630 bar (9000 PSI), suitable for high-pressure hydraulic systems in construction machinery, oil & gas, and heavy equipment.
4. Standardized Design
Strictly complies with DIN 2353/ISO 8434 international standards, ensuring global compatibility and interchangeability with hydraulic systems.
Typical Applications
Hydraulic Power Units (HPUs)
Industrial machinery high-pressure piping
Mobile equipment (e.g., excavators, cranes)
Key Advantages
1. Right-angle design saves installation space
2. Dual-end sealing for secure leak prevention
3. High-pressure endurance for harsh conditions
4. Standardized interfaces for easy maintenance
This product is an ideal solution for high-pressure hydraulic connections, balancing performance and reliability.
