A-2
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.

Specifications
- Rubber grade: EPDM, NBR or CIIR rubber
- Range: DN 20 to DN 1000
- Temperature: max. 100°C
- Pressure stage: PN 16
Application
Stenflex rubber expansion joints type A-2 or A-4 are generally applicable and well suited for absorbing vibration from pumps, absorbing ground settlement or lateral pipe displacements.
