Technical Specifications

Design and Operating Principle

Full face rubber expansion joint designs are optimized with an elastomer body that fully covers the flange face, ensuring high sealing performance.

The flexible elastomer structure absorbs thermal expansion, vibration, and mechanical movements, reducing stresses on piping and equipment connections. It also helps dampen vibration generated by pumps and valves.

Thanks to the full face design, bolt hole alignment becomes easier and secure installation is achieved without the need for additional gaskets.
