Duct Seals – Filoform MDI Water & Gas Cable Duct Sealing Kits

Filoform MDI is a watertight and gastight cable duct sealing system developed for sealing ducts containing pliable cables such as coax and rubberised cables which can be easily bent to a right angle.

The MDI duct seal system allows these cables to be sealed anywhere along a wall where the cable enters a building and is suitable for ducts with a diameter of 16mm up to 32mm and cables or pipes with a diameter up to 25mm.

This duct sealing system is specified and used by major Electrical, Gas, & Water Utililty companies in the UK and Benelux countries.
