JIS 10K Flanged Double Sphere Rubber Expansion Joint EPDM Vulcanized for Water Supply Systems

Product Description:

This JIS 10K Flanged Double Sphere Rubber Expansion Joint is manufactured through high-temperature molded vulcanization, forming a seamless single-body rubber bellows with consistent quality and reliable sealing. The vulcanized EPDM body delivers high elasticity, corrosion resistance and long service life for water piping systems.

The double sphere design provides large axial displacement and angular deflection, effectively absorbing vibration, reducing noise and compensating for thermal expansion and pipeline misalignment. The reinforced structure with multi-layer nylon cord fabric and steel wire strand ensures stable performance under pressure fluctuation.

The flanged connection is produced strictly to JIS 10K standard, ensuring accurate bolt hole spacing and sealing face dimensions for direct installation on Japanese standard piping systems. The joint also supports gas tight sealing with zero leakage performance, suitable for both water and air media.
