High quality Filoform Filoseal+ Duct Sealing products

What is the Filoform Filoseal+ Duct Sealing?


The FiloSeal+ duct sealing system is a universal solution for sealing cables and pipes in ducts or bore holes of 150-200mm.

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

The Filoform duct sealing system uses the Filoform MD+ sealant which is easily applied from a standard skeleton gun. The high quality, one component, flexible sealant is based on a silicone compound that air-cures. 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+ is very easy to apply regardless of the type of cable scenario in the cable ducts as it uses a uniquely shaped foam piece which positions neatly around the cables or pipes in the duct. The unique design of the tri-flexible foam makes positioning and separation of the cables very simple while also providing a backing for the MD+ to be applied on.

This seal is also easily installed in vertical scenarios while providing the added security of ensuring no loss of components down the duct.
