Molded Rubber Coupling Joints Expansion

Double Sphere Flexible Rubber Joint for Axial/Horizontal/Angular Movement Capability

Product Description:

The Expansion Double Sphere Joint is a testament to engineering excellence, providing a combination of flexibility, durability, and reliability. Its double sphere design allows for greater axial, lateral, and angular movement compared to single sphere models, thereby offering superior shock absorption and vibration isolation. This design also contributes to the reduction of noise, a common issue in high-flow systems, thereby creating a more pleasant working environment.

Our Advantages:

Rich production experience
Professional technical team
Effective cooperation between logistics departments
High quality product accessories
Excellent corrosion resistance
Excellent shock absorption effect
Good after-sales service
Extremely high industry reputation
