LSF Low Smoke Zero Halogen

For Low Voltage Cable Splices, Cable Repair & Insulation Protection

3M Silicone Cold Shrink Tubes are open-ended, silicone rubber, tubular sleeves used to seal cables, connectors, glands and lugs providing LSF (Low Smoke & Fume) seal.

Simply unwind the core and the 3M Silicone Cold Shrink Tube shrinks to form a tight seal around the cable, lug, connector or gland.
