Stenflex rubber expansion joint type C-231

Product information

Stenflex rubber expansion joint type C-231 is a two-wave rubber expansion joint with full rubber flanges and tension rods, available in large diameters for large displacements. Various flange drillings are possible in this set-up. Thanks to the tension rods, the pressure reaction force is absorbed in a system. The tension rods are only limited on the outside as a standard, so that the expansion joint cannot extend.

Stenflex rubber expansion joint type C-231 is available in three different pressure ratings, whereas the overall length can be customised. Optionally, the tension rods can be limited on the outside, as well as on the inside. This way, the expansion joint cannot extend and cannot be pressed in (e.g. in a vacuum).
