Stenflex rubber expansion joint type Ai-2 or Ai-4

Product information

Stenflex rubber expansion joint type Ai-2 and type Ai-4 are standard rubber expansion joints with PTFE inlays, rotatable flanges and tension rods. Various flange drillings are possible in this set-up. Thanks to the PTFE inlay there is no direct contact between the medium and the rubber bellows. Thanks to the tension rods, the pressure reaction force is absorbed in a system.

Type Ai-2 or Ai-4:

  • With type Ai-2, the tension rods are only limited on the outside, so that the expansion joint cannot extend.
  • With type Ai-4, the tension rods are limited on the outside as well as on the inside, so that the expansion joint cannot extend and cannot be pressed in. As in the case of a vacuum.
