Filofast thermoshrink joints
The Filofast joints have been developed for telecom networks, which is based on a special sealing material. This joint offers many advantages against other jointing methods existing in the market. Installation is easy, and the result is extremely reliable. Filofast joints can be used for both straight and branch connections.
- Saving on installation time up to 25%
- Fewer components
- No adhesive rings or scops required
- Reliable and long lasting sealing against water penetration
- Low risk of cable damage when shrinking the material round the connection.
- Long lasting flexible seal
- Only one installation method for all cable types
- Easy to re-enter the joint if needed:
- Upon request,we can adapt the kit & componets to suit your requirements

| More information | In all our heat shrink products, we start from the principle that the products must be reliable and as good as the cable itself. The high quality of the heat-shrinkable products, and to the detailed instructions for use comply with this principle. The large and complete range of heat shrinkable products consists of connecting, transitional and end sleeves and various products for various cable constructions. The products include all necessary materials for a perfect protection of the cable. The shrinkable products are manufactured from high quality raw materials with very high cross-linking and can be provided with an internal coating if required. Depending on the application use these internal coating consist of an adhesive layer, or a mastic layer. The production is carefully monitored according to ISO 9001
