Cable Duct Seal Kits
Filoform MDI Water & Gas Duct Seals
Filoform MDI is a watertight and gastight duct seals are 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 60mm and cables or pipes with a diameter up to 25mm.
This water and gas cable duct seal kit is specified and used by major Electrical, Gas, & Water Utility companies in the UK and Benelux countries.
