Product information

Stenflex rubber expansion joints type A-2 (and type A-4) are standard rubber expansion joints with rotatable flanges and tie rods. Various flange bores are possible here. Thanks to the tie rods, the pressure reaction force in a system is absorbed and the expansion joints can only absorb lateral displacements.

Type A-2 and Type A-4:

  • In Type A-2, the tie rods are limited only on the outside, which prevents the expansion joint from extending.
  • In the type A-4, the tie rods are bounded both on the outside and on the inside, preventing the expansion joint from lengthening and compression. As in vacuum.
