Corrugated gaskets
files/1563/en/DIMER_Industrial_gasket_Corrugated_gasket.jpg


Semi-metallic corrugated gaskets of the DIMERFLEX NT series are universally applicable sealing elements for lower operating pressures, but in case of a suitable composition of the corrugated core (metal sheet) and the sealing material they can be used for pressures up to 140 bar.

Corrugated gaskets are produced in a variety of profiles and sizes in circular, oval, elliptical, square or rectangular frame shapes including internal ribs, with/without holes or fixing loops, in combination with flat sealing elements, or even with static insulation packings.

This products family is continuously growing and many improvements have been implemented to cover all customer needs.

We are ready to recommend, design and produce the shape you desire.
