Made of high-quality Silicone rubber material, this sleeve offers exceptional weather resistance, as well as resistance to acids and alkalis. It is pre-expanded and assembled onto a removable core, allowing for easy installation over a cable connector or terminal lug. Once positioned, the core is removed, and the rubber sleeve shrinks onto the connector, forming a tight and secure seal.
With its excellent sealing properties, the Tubular Rubber Sleeve is an ideal choice for various types of connections. Whether you need to protect wire and cable connections in telecommunications or power applications, or any other type of connection requiring a waterproof seal, this sleeve is the perfect solution.
