  • Product Description
    Expando® 2621 offers maximum resistance to abrasion and impact damage without sacrificing the valuable features provided in traditional Expando products. Rated to +125°C and featuring a dual-monofilament construction, Expando 2621 smoothly blends tougher, nylon (guard) strands with customary resilient polyester (support) strands. The carefully calculated mix of guard strands and support strands provides an excellent balance of key features including toughness, expandability, resilience, and flexibility.

    Bentley-Harris    ® Expando® products are tough, lightweight oversleeves used to protect cable assemblies, hoses and wire harnesses from chafing, cutting and abrading. The open-braid construction of Expando products enables each size to expand to fit several application shapes and sizes. This open-textile construction also makes them highly flexible and resistant to trapping water, heat and humidity.

    Expando 2621 extends the service life of fluid, hydraulic, pneumatic or thermally insulated hoses, and wire harnesses where physical abuse is the major hazard. This product should be considered wherever handling, repeated flexing, abrasion, impact or similar hazards indicate a need for a high performance protective oversleeve. Expando 2621 is ideally suited for applications in electronics, marine, vehicular and industrial environments.
