Expando DM Protective Sleeve: Ultimate Wear Resistance and Flexibility

Expando DM protective sleeve offers maximum protection against abrasion and impact damage while retaining the valuable properties of traditional Expando products. With a rating up to +125°C and a dual-monofilament construction, Expando DM combines strong nylon protective strands with resilient polyester support strands. This carefully balanced mix provides an optimal balance of strength, expandability, resilience, and flexibility.

Unmatched Protection for Various Applications

Bentley-Harris® Expando® products are robust, lightweight oversleeves that protect cable assemblies, hoses, and wire harnesses from abrasion, cutting, and other forms of damage. The open braid construction allows the sleeve to stretch to fit different applications and sizes while remaining flexible and resistant to water, heat, and moisture.

Ideal for Demanding Environments

Expando DM extends the life of fluid, hydraulic, pneumatic, or thermally insulated hoses and wire harnesses in situations where physical abuse is the greatest risk. This protective sleeve is perfect for applications in electronics, shipping, vehicles, and industrial environments, where repeated bending, impact, and abrasion require high-quality protection.
