3M 8454 Cable Accessory Sealing Kits
Categories: Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)

Material Notes: 3M Cable Accessory Sealing Kits provide a reliable means of sealing the jacket end of power cables where elbows or other cable accessories are installed. The seal is accomplished with use of tubular rubber sleeve and rubber base mastic sealing strips. The mastic strips seal around cable neutral wires or other ground attachment leads. The rubber sleeve is factory expanded and assembled onto a removable core. As supplied in this pre-stretch conditions the tube is ready for field installation. With mastic in place, the expanded tube is positioned over the cable jacket end and the inner supporting core is removed. Removing the core allows the sealing tube to shrink and form a water-resistant seal. The sealing tube is made of EPDM rubber that contains no chlorides or sulfur. Both the sealing tube and mastic are compatible with commonly used power cable jacket and semi-conductive materials. To extend the useful life of this product in applications which are continuously exposed to high levels of ultra-violet radiation, overwrap with Scotch Super 33+ Vinyl Tape or Scotch 70 Silicone Tape.
