FiloSeal+HD is an engineered solution that provides a strong support system using the hexagonal tubes which builds up like a honeycomb structure. FiloSeal+HD  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 uses our MD+ sealant which is easily applied from a standard skeleton gun. The high quality, one component, flexible sealant “MD+” is based on a silicon compound that cures with air (Humidity).

After application and full curing the thixotropic MD+ forms a plastic elastomer mass with special qualities effectively sealing and bonding, while providing a high level of durability.


FiloSeal+HD is very easy to apply regardless of the type of cable scenario in the cable ducts as it uses strong, but flexible hexagonal tubes to support the cable and provide a strong backing for the seal

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