It is an open-end tubular rubber sleeve, which is pre-expanded and assembled onto a removable core. The core is removed after the tube has been positioned for installation over a cable connector, terminal lug, etc., then the rubber tube shrinks onto the connector 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 wire and cable connection in telecommunication and power field, and kinds of other types of connections
