3M Cold Shrink Connector Splice Insulator, EPDM Rubber

3M Cold Shrink Connector Splice Insulator, EPDM Rubber

The 3M Cold Shrink Connector Splice Insulator insulates and protects electrical connector splices without heat guns, torches, or other special tools. Installers remove an internal supporting core and the tube shrinks down to conform tightly around the connector body. Offered in two wire-range options — 6-4 AWG (14-16 mm²) and 10-1/0 AWG (6-16 mm²) — this cold shrink insulator lets electrical contractors, utility crews, and maintenance technicians match coverage to the connector size on the job. Molded from EPDM rubber with a 2:1 shrink ratio, it is rated for low-voltage connector splices.

Key Features

• Wire Range Options: Available in 6-4 AWG (14-16 mm²) and 10-1/0 AWG (6-16 mm²) configurations, covering a broad span of connector sizes.
• Cold Shrink Design: Installs without heat, flame, or specialized tools — remove the internal core and the insulator shrinks into place around the connector.
• Durable Construction: Molded from EPDM rubber for flexible, weather-resistant coverage over the connector splice.
• Shielding Type: Tape shield configuration helps maintain shielding continuity across the splice.
• Shrink Ratio: A 2:1 shrink ratio delivers a tight, conforming fit over connector bodies of varying diameters.
• Operating Temperature: Rated from -40 to 90 degrees celsius (max. 194 degrees fahrenheit), suited to demanding field environments.
• Case Packaging: Supplied 10 per case for convenient field inventory across multiple splice locations.
