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

Product information

Stenflex rubber expansion joint type A-2 and type A-4 are standard rubber expansion joints with rotatable flanges and tension rods. Various flange drillings are possible in this set-up. Thanks to the tension rods, the pressure reaction force is absorbed in a system and the expansion joints can only absorb lateral displacements. 

Type A-2 and type A-4 : 

  • With type A-2, the tension rods are only limited on the outside, so that the expansion joint cannot extend.  
  • With type A-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.  
Stenflex A-2


  • Rubber grade: EPDM, NBR or CIIR rubber 
  • Range: DN 20 to DN 1000 
  • Temperature: max. 100°C

Stenflex rubber expansion joint types A-2 or A-4 are for universal use and well suited for absorbing vibrations from pumps, absorbing subsidence or lateral pipe displacements.
