Rubber compensator Type A-1Universal compensator DN 20 – DN 1000

 for reducing thermal and me-chanical tension in pipes andtheir system components, e.g. pumps compressors motors

 for absorbing vibration andnoise

 for compensating axial, lateral

and angular movement for compensating simultaneous

movement in cooling waterpipes

 to compensate for installationinaccuracies
