Cold Shrink Connector Insulators

8420 Series

Data Sheet

1. Product Description

Insulators are open-ended, tubular,

rubber sleeves which are factory

expanded and assembled onto a

removable core. The core is removed

after the tube has been positioned for

installation over an inline connection,

terminal lug, etc., allowing the tube to

shrink and form a water-resistant seal.

The insulating tube is made of EPDM

rubber which contains no chlorides or

sulfurs. Six diameter sizes will cover a

range of 1000 volt cable from 10 AWG

through 1000 kcmil, copper and

aluminum conductors.

To extend the useful life of this product

in applications which are continuously

exposed to high levels of ultra-violet

radiation, overwrap with Scotch

33+ Vinyl Tape or Scotch

Tape.

Features:

Simple installation, requires no tools.

Accommodates a wide range of cable

No torches or heat required.

Good thermal stability.

Seals tight, retains its resiliency and
