Doyma Gasket Inserts.


Seal off intelligently – simply and safely

Doyma Gasket InsertsDOYMA Curaflex® is a synonym for safe sealing of building penetrations for pipes and cables. Curaflex® gasket inserts are indispensable for sealing off supply and disposal lines in the following sectors: building and civil engineering, sanitation, heating, air conditioning, ventilation, piping.

Functioning principle
The rubber seals located between the medium pipe and the pipe sleeve or the core bore, and the two profiled steel rings in the installation condition are then pressed together by tightening the nuts. The rubber then closes the gap between the media pipe (cable or cable conduits) and the pipe sleeve or the core bore securely. Re-tightening is no longer necessary.



Only Curaflex® gasket inserts are fitted with steel ring profiles on both sides. They ensure optimum contact pressure – caringly towards the media pipe and strongly towards the core bore/pipe sleeve (up to DN 350).


Specially for DOYMA developed ageing resistant elastomer prevents the gasket insert from slipping under load due to friction-reducing substances.

Typical application areas

gas and water pipes drainage pipes heating and district heating pipes electrical cables, cable conduits shaft structures Sewage works

Capacity range

against pressing and non-pressing water in built-in pipe sleeves in waterproof concrete core bores for applications with waterproof membranes (white tanking) or thick coatings (black tanking) gas-tight against any gases which do not attack the material (e.g. air, nitrogen, noble gases) angles of 8° are possible, maintenance free, without re-tightening


DoymaEasily installed – intelligent adjustment

DOYMA has achieved a new stroke of genius: Curaflex Nova® Multi. Curaflex Nova® Multi will inspire designers and contractors alike. Now it is easier than ever to plan more accurately – because there are just two parameters needed for sealing pipe entries into a building: the pipe outside and the core or sleeve inside diameters.

This is all that’s neccessary to ensure the right solution on site. Even unforeseen situations with different sizes of service pipes cvan be readily accommodated, easily and flexibly.

High-performance plastic

Lengthy and often cosly delays are now simply eliminated. Another novelty: the frame is made of special high-performance plastic that has outstanding chemical resistance. Very important: Curaflex Nova® Multi masters all pressure conditions, no matter whether pressing or non-pressing water.
