Heat shrink tubing makes your wiring look neat and professional. DEI's Hi-Temp Shrink Tubing shrinks down when heated to form a tight seal that protects your wire splices and connections from short circuits and moisture. You can also bundle wires together in harnesses without messy electrical tape.
These black heat shrink tubes come in 4-foot lengths and are available in 3 mm (approx. 1/8"), 6 mm (1/4"), and 9 mm (3/8") diameters, as well as an assortment package that includes all three sizes. For splicing, use the 3 mm size for 16-gauge wire, 6 mm for 10-gauge, and 9 mm for 8-gauge. Warranty: 30 days.
