3M Cold Shrink Quick Insulator QI 5/16-220, 1 kV, 10 per case

3M™ Cold Shrink Quick Insulator QI Series are open-ended tubular rubber sleeves with sealing mastic on each end that are factory expanded and assembled onto a removable core. The core is removed by pulling from one end after the QI insulator has been positioned over an inline connector, allowing the ends of the tube to shrink and form a water-resistant seal. Sizing of the core and tube, along with the sealing mastic on each end, provides a broader application range without degrading the seal and insulating characteristics of the EPDM rubber tube. Five diameter sizes will cover a range of 1 kV or less cable from 8 AWG–3000 kcmil, copper and aluminum conductors with crimped connectors.
