Ancor marine grade adhesive lined heat shrink tubing seals electrical connections against moisture intrusion and corrosion. Heat shrink along with dielectric grease on wire strands yields the maximum barrier against wire connection failure. Ancor's tubing is made from a material that is stronger than PVC tubing and will not burn like PVC tubing. The heat activated lining inside provides an impervious barrier to water, oil, acids, and sunlight.

This heat shrink tubing is essential to have on a boat, RV, camper, or anywhere else water or fluids might be present and a potential danger to electrical connections. A variety of diameters and lengths are available.
