3: Lined Dual-Wall Heat Shrink Tubing Roll 10M — 31 Shrink Ratio

10M roll of lined dual-wall heat shrink tubing engineered with a 31 shrink ratio, contracting to one-third of its original size when heated to provide increased tensile strength and resistance to stretching and vibration. Constructed from PE with an inner meltable layer, the tubing forms a waterproof seal around splices and connectors to protect against moisture and other environmental factors. Rated for temperatures from 67 to 257 degrees Fahrenheit, this flame-retardant tubing produces minimal smoke during use. Simple to apply — slide over wires or terminals and apply heat to create insulated, sealed connections ideal for both quick repairs and professional installations.
