Quadrios 201711CA003 3:1 Heat Shrink Tubing Assortment, Black, 100 Pieces

Electrical connections exposed to moisture, dirt, or movement fail early. This Quadrios heat shrink tubing assortment seals and insulates splices, terminals, and cable bundles with a 3:1 shrink ratio that conforms tightly to irregular shapes. The black polyolefin tubing recovers to 1/3 of its supplied diameter, providing strain relief and protection against abrasion and corrosion.
