Commercial Electric 12-6 AWG Heavy-Wall Heat-Shrink Tubing, Black (2-Pack)

Commercial Electric's adhesive-lined heavy-wall heat shrink tubing is engineered for tough environments and delivers superior insulation, sealing, and protection for wire splices, terminations, and cable repairs. Made from durable, cross-linked polyolefin, it features a thick outer wall for abrasion, impact, and chemical resistance. The inner adhesive lining melts and flows when heated, bonding to surfaces and sealing out moisture, dirt, and contaminants-even in direct burial or submersible applications. Flame-retardant and UV-resistant, it's ideal for automotive, marine, industrial, and underground electrical installations where long-term reliability is critical.
