The Heat Shrink Kit is a heat-shrinkable tubing for insulating and sealing L-823 type plug and receptacle electrical connectors. The medium wall tubing is designed for a variety of low voltage cable applications where lighter weight and greater flexibility are important. The tubing is made from a thermally stabilized, modified polyolefin.
• Mechanical protection: high impact and abrasion resistance of tubing provides excellent mechanical protection. It also provides additional strain relief.
• Environmental seal: sealant provides excellent waterproofing and environmental protection in submersible and buried applications.
• Superior adhesion: thermoplastic adhesive will adhere to all standard plastic, elastomeric insulating material, lead, steel, aluminum and copper.
• Easy to install: when heated above +248°F (+120°C), the tubing shrinks rapidly to seal and encapsulate electrical connections. This provides a fast, simple and clean insulation system. The tubing will not split or rupture during normal installation, even when overheated.
