"Ancor Marine Adhesive Lined Heat Shrink Tubing (alt) Tubing, 3/8"" X 3""l, Black/red (1/1 Qty/pk)"

"Ancor Marine Adhesive Lined Heat Shrink Tubing (alt) Tubing, 3/8"" X 3""l, Black/red (1/1 Qty/pk) . Ancor s adhesive lined tubing is superior to conventional heat shrink tubing. It s made from cross-linked polyolefin, which is much stronger than PVC. With a 3:1 shrink ratio, it can shrink up to one-third of original size. The waterproof adhesive is heat-activated. It bonds tenaciously to insulating covers and terminals, producing strain relief that makes a stronger connection than the mechanical connection alone. Shrinks at 257F, safely below the temperature at which insulation melts."
