    Description
    Gebhardt-Stahl Premium-Flange 20 D – the result of consistent further development of our existing flange systems. We have created a unique slip-on flange system with a clinched joint and a double-beat.

    The Premium flanges with injected Butyl-sealant fulfil the highest requirements with regard to tightness and easily achieve sealing class D in accordance with DIN EN 1507 (TÜV-Nord certified).

    In addition, our Premium-Flange have another special feature: the torsional rigidity of these flanges is 20 times higher, compared with our conventional slip-on flange. Also, as a result of the clinched joint, an extremely rigid corner chamber is formed, thus the flanges and corners form a rigid unit after being plugged together. The handling and assembly characteristics of the flange frames are positively influenced by the increased stiffness.

    The injected Butyl-sealant of our Premium-Flange 20 D meets the requirements of DIN EN ISO 846, is solvent-free, silicone-free and permanently elastic.
