Description
Oil and Acid Resistant Pn16 Carbon Steel Flexible Concentric Reducer Rubber Coupling
Tetrafluoroethylene has excellent chemical resistance and corrosion resistance, and is one of the most corrosion-resistant materials in
the world today.It can all other chemicals except for melting and liquid tetrafluoroethylene, and does not change when boiled in
strong water. F4 can effectively prevent the medium inside the pipeline from corro the rubber joint, improve its corrosion resistance,
and resist the erosion of most chemical media.
Key Features:
  • Good elasticity for vibration and noise reduction
  • SS304 flange connection
  • Single sphere rubber expansion bellows design

DN25-DN3000 Flange End Flexible Joint Rubber Expansion Bellows

Product Description
Rubber expansion joints consist of inner and outer rubber, cord layer and steel wire strand, which are vulcanized and then combined with
metal flangesor loose sleeves of parallel joints. It is widely used in various pipeline systems.

DN25-DN3000 Flange End Flexible Joint Rubber Expansion Bellows

The rubber expansion joints allow for four way movements, and they are molded from synthetic rubber and nylon cord. This
design reduces vibration and noise, and compensates thermal expansion and contraction caused by temperature change.
