The Double Sphere Flange Type Rubber Joint is a high-performance flexible connector engineered to absorb vibration, compensate for axial and lateral displacement, and reduce noise in piping systems. By utilizing a dual-sphere design, it provides superior flexibility and stability compared to single-sphere alternatives, making it an essential component for industrial piping infrastructure.
Constructed from premium polarized rubber reinforced with nylon cord fabric and hard steel wire, this rubber joint ensures exceptional durability and pressure resistance. Whether utilized in water distribution, HVAC systems, or industrial processing, it effectively prevents pipeline misalignment and protects equipment from mechanical stress caused by thermal expansion or seismic shifts.

Frequently Asked Questions
PN10 and PN16 refer to the nominal pressure ratings in bars. PN16 is designed for higher pressure environments (up to 16 bar), whereas PN10 is suited for systems up to 10 bar.
The double sphere design increases the joint's flexibility, allowing for greater lateral displacement and angular deflection, which effectively reduces stress on the connected pipes.
We use polarized rubber for the main body, reinforced with nylon cord fabric for tensile strength and hard steel wire for structural integrity, combined with forged steel flanges.
The temperature limit depends on the specific rubber compound. Our polarized rubber is designed for industrial durability, but we recommend consulting our technical specs for specific medium temperature limits.
We recommend a visual inspection of the bolts and flange alignment every 6-12 months, depending on the vibration levels of your specific system.
Yes, our range extends up to 600mm (24 inches). For requirements beyond our standard chart, please contact our engineering team for custom manufacturing options.
