Manhole seal: various materials 

We supply manhole gaskets in the following materials:

Rubber
Our rubber manhole gaskets can be produced out of any desired rubber grade. The gaskets can be supplied in different shapes. Also in large dimensions. The manhole seals are suitable for various applications, such as the maritime and offshore industry. But also in heated water installations, dryers and hot air systems.

Flangiflon (PTFE)
The material of this gasket has a unique fiber structure. This provides both an exceptionally good chemical resistance and temperature resistance. The material is steam-resistant which makes these gaskets perfectly suitable for use in steam boilers. Our Flangiflon manhole seal is endless.
