KE232082427, 3M Cold Shrink Tubing, Black 49.3mm Sleeve Dia. x 152mm Length, 8420 Series

3M Rubber Cold Shrink Connector Insulator

The 3M 8420 series black 152mm cold shrink connector insulator is an open-ended, tubular, rubber sleeve. It is factory expanded and assembled onto a removable core. The core is removed after the tube is positioned for installation over an inline connection and terminal lug. This allows the tube to shrink and form a water-resistant seal. The insulating tube is made of EPDM rubber, which contains no chlorides or sulphurs. It is available in diameter sizes that cover a range of cable up to 1000V for copper and aluminium conductors.

Features and Benefits

• Sleeve diameter is 49.3mm
• Shrunk diameter is 24mm
• Excellent wet electrical properties
• Good thermal stability
• Improved, tougher rubber formulation to withstand backfilling
• No mastic or tape required to seal
• No torches or heat required
• Resists acids and alkalis, resists ozone
Seals tight, retains its resiliency and pressure even after prolonged years of aging and exposure
• Simple installation, requires no tools
• Water-resistant
• Tough rubber formulation withstanding rough backfilling

Applications

Heat shrink tubing is frequently used to weatherproof or otherwise protect exposed connections or cable ends. It is an efficient way to seal or reinforce wiring that is not covered by a cable sheath, and so is used in many kinds of electrical installations, from manufacturing to domestic wiring. This heat shrink tubing is often used for;

• Dig-in repairs
• Direct burial or submersible. For indoor and outdoor
• Environmental sealing for communication and other non-electrical applications
• Insulation of secondary splices, copper, or aluminium conductors
• Physical protection and moisture sealing for air-insulated connectors and lugs such as spacer cable and lug connections to bus bar
• Primary electrical insulation for all solid dielectric (rubber and plastic) insulated wire and cable splicing rated to 1000V
• Relocation of service
• Sheath repairs

Certifications

NEMA Pub. No. PP-C1
Meets the water seal requirements of ANSI C119.1
