Our cold shrink tube can be customization, it provides reliable weatherproofing for low voltage power and coax connectors and cables. Installation does not require tooling, is quick and easy, and the quality of the installation is less installer dependent.

Replace 3M CXS series, 8420 series, 98-KC series . UV resistant.

It is a series of insulated rubber sleeves which are factory expanded and assembled onto a removable core. They are supplied for field installation in this pre-stretched condition.

The core is removed after the tube has been positioned for installation over a cable connection, terminal lug, etc., allowing the tube to shrink and form a waterproof seal.

It is made of Silicone rubber material, which have excellent weather resistance, acid and alkali resistance. It is ideal sealing material for the communication cable, coaxial cable, medium voltage and low voltage power cables.

Cold Shrink Silicone Tubing
