This 3/16″ ID 2.5:1 semi-rigid heat shrink tubing features an internal adhesive lining that forms a secure seal when heated, protecting wire splices and terminals from water, corrosion, and abrasion. Its rigid polyolefin outer layer provides enhanced mechanical strength, while the tubing remains flexible enough to conform to uneven surfaces. Ideal for automotive, marine, and industrial wiring applications requiring extra durability.
