Heat Shrink

Finish your fishing electronics installation project with heat shrink tubing for insulating wire splices and covering electrical connections. Whether you’re installing a fish finder, upgrading your walleye boat’s electronics, or tidying up existing wiring, heat shrink helps give your rigging a clean, organized finish.

Choose tubing with an expanded diameter that fits over your connection and a recovered diameter that fits snugly after shrinking. Check each product’s shrink ratio, temperature requirements, and adhesive-lining specifications. For boat wiring exposed to moisture, look for adhesive-lined options rated for the application and follow the manufacturer’s installation instructions.
