3M Cold Shrink Tubings

3M Cold Shrink tubes are a series of open-ended, tubular rubber sleeves which are factory expanded and assembled onto a removable core. 

3M Cold Shrink tubes are supplied for field installation in this pre-stretched condition - the core is removed after the tube has been positioned for installation over an inline connection or terminal lug allowing the cold shrink tube to shrink and form a waterproof seal - no heat shrink gas torches or hot working required.

3M Cold Shrink insulating tubes are available in both EPDM rubber and silicone.

Cold shrink tubes typical applications : primary electrical insulation for rubber and plastic insulated splices up to 1000 volts, directly buriable or submersible, moisture sealing for high voltage air insulated connectors and lugs, dig-in repairs, cable sheath repairs and waterproof sealing of low voltage rail cables.

3M Cold Shrink Cable Sealing Tubes are specified for rail cable sealing, insulation and protection and are approved by Network Rail for live rail terminations and inline cable joints for DC track feeder cable applications.

3M Cold Shrink provides a permanent radial seal, expanding and contracting with the rail cable under load conditions - 3M Cold Shrink Tubes are made from EPDM rubber, expanded onto a removable supporting plastic core.

As the core is unwound, the 3M Cold Shrink insulating sleeve shrinks to form a tight seal around the cable, terminal or splice.

• 3M Silicone 8770 Cold Shrink Tubing - resists fire, self-extinguishing, anti-tracking up to 33kV, hydrophobic surface (repels moisture) and UV stable for outdoor cable applications. 

• 3M EPDM Rubber 8420 Cold Shrink Tubing - resists moisture, acids, alkalis and UV light, suitable up to 1000 volts, thick walled tubing resists puncture and ideal for use in cable duct sealing applications.
