dual sphere  rubber epdm

Feature :

1.Small volume,light flexible ,easy to install and maintain

2.It reduces structural noise transmission with strong shock absorption in servive.

3.It is capable of horizontal,axial and angular displacement with the restruction and flange non-parallelism.

4.The inner seamless high-pressure rubber joint independently developed by us prevents corrosive medium from etching the inner wall of the rubber joint in high temperature ,acid and alkali and oil resistant pipeline,thereby extending its service life .
