Structure

Two molded rubber rings are sandwiched between flanges from both sides to ensure tightness between the main and sheath pipes by tightening the bolts.

Characteristics

• Compared to the filler method, the work time can be significantly reduced.
• No centering is required because of the concentric circles.
• The main pipe and the sheath pipe are prevented from contacting each other and insulated with anti-corrosion effect.
• The seal between the main and sheath pipe is strong, preventing the inflow of earth and sand.
• It absorbs vibrations and protects the main pipe from earthquakes and ground vibrations.
• It can be used for any kind of pipes.

Main applications

• As fixing (support) material and sealing material for the pipe ends of all duplex structures.
• Sealing, shock-absorbing, and vibration-absorbing materials for wall penetrations such as building walls, manholes, pits, and common ditches.
