3M™ COLD SHRINK PST SILICONE INSULATOR, 0.4/9/1.3 IN, 100 EA/CASE

3M™ Cold Shrink Quick Insulator QI Series consists of open-ended and factory-expanded tubular rubber sleeves that feature sealing mastic on each end loaded on a removable plastic core. To install the connection, position it over the inline connector, pull the loose tab on the plastic core while unwinding the core in a counterclockwise direction, allowing the ends of the tube to shrink and form a secure seal. The core and tube sizing, combined with sealing mastic at each end, allow for a broader application range while preserving the seal and insulation properties of the EPDM rubber tube. Designed for primary insulation of solid dielectric insulated wires and cable splices rated up to 1000 volts, the insulators allow for direct burial or submersible applications. They are easy to install by hand, requiring no additional tools or heating sources. Accommodating a variety of cable sizes, 3M™ Cold Shrink Quick Insulator QI Series provides reliable thermal stability, high chemical resistance, and a water-resistant seal that meets the standard for ANSI C-119.1. These insulators are ideal for dig-in and sheath repairs, inline conductor transition connectors, and secondary splices for both copper and aluminum conductors, withstanding an operating temperature range between -40 °F to 194 °F (-40 °C to 90 °C). When you need dependable insulating properties with long-lasting resiliency and pressure performance, 3M™ Cold Shrink Quick Insulator QI Series is your go-to solution.

3M has over 40 years of lab-tested and industry-proven results demonstrating the reliability of cold shrink technology. 3M™ Cold Shrink Quick Insulator QI Series and the other products in the cold shrink family are engineered with specially formulated materials that deliver a durable environmental seal and insulation. Five diameter sizes accommodate cables up to 1000 volts, ranging from 8 AWG to 3000 kcmil, for both copper and aluminum conductors with crimped connectors. For applications with high UV exposure or where visual inspection isn't feasible, it is recommended to overwrap the tubing with Scotch® Super 33+™ Vinyl Electrical Tape or Scotch® Self-Fusing Silicone Rubber Electrical Tape 70.
