EPDM PN25 Concentrically Reduced Rubber Joint Shock Absorption
Concentrically Reduced Rubber Joint is generally consists of the inner and the outer rubber layer and fabric reinforced layer (the enhancement
layer has a multilayer cord fabric), vulcanization molded in high temperature and high pressure , then assembly together with
rubber tube and metal flange.
Features of Concentrically Reduced Rubber Joint
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.
