FiloSeal+ HD FIRE provides a strong support system using our specially formulated material called Formite which builds up like a honeycomb structure.


FiloSeal+ HD FIRE is suitable for sealing any cable configuration or pipes contained in one duct and also allows easy re-entry of the seal to add or remove cables or pipes as required.

The Filoform duct sealing system FiloSeal+ HD FIRE uses our MD+ sealant which is easily applied from a skeleton gun. The high quality, one component, flexible sealant “MD+” is based on a silicon compound that cures with air (Humidity).

The unique design of the hexagonal tubes makes position and separation of the cables very simple while also providing a strong backing for the MD+ to be applied on
