  • Product Description
    TwistTube® 2421 is a self-closing oversleeve designed to provide mechanical protection and to suppress acoustic noise. Woven of monofilament and multifilament polyester yarns the product offers superior abrasion protection, high level of component protection and is both flexible and lightweight. Its unique construction eliminates problems associated with trapped heat and humidity.

    TwistTube 2421 fits tightly to wire harnesses, saving space, but without reducing the flexibility of the wire bundles it protects. It also maintains a circular profile when flexed. Its self-wrapping design allows for quick and easy bundling of wire and cable assemblies. The unique design easily allows for breakouts and can be installed over completed assemblies.
