Better than electrical tape by far!
Used this on vehicles (starters) and trailer lights. Easy to use, looks like a professional fitting, and seems to hold tight.

Helixal — Professional Heat Shrink Tubing
Helixal — Professional Heat Shrink Tubing
Helixal 3:1 ratio heat shrink tubing with adhesive lined dual wall construction — in 10ft rolls. Try a size before buying bulk. Handle spot repairs without storing excess. Stock every diameter you need.
Every value is per-lot tested. Spec sheet matches catalog matches lab. No marketing variance.
Cut tube 20–30% longer than the area to cover. Tubing contracts slightly in length as well as diameter when heated.
Thread tubing over the wire or component before making the splice. It cannot be fitted after the connection is made.
Center the tube over the joint, leaving at least 20mm of coverage past the connection on each side.
Apply even heat with a heat gun until the tube contracts fully and adhesive flows from both ends — confirming a watertight seal.
Emergency on-board wire repair, single connector sealing, bilge sensor protection, and navigation light terminal work.
Single harness repairs, trailer hitch connector sealing, battery terminal protection, and classic car restoration across multiple gauges.
Order 10ft in two candidate sizes, test them on your connector, then commit to the large roll in the size that fits.
A repair needs 6 inches. A 10ft roll is manageable — use what you need, store the rest in a tool bag. No excess shelf stock.
For the same price as one large roll, stock five or six different diameters — every connector you encounter, covered.
Home electronics repair, maker projects, and low-volume professional installs where a large roll would go to waste.

Good quality and sealing heat shrink
Heat shrink works good. Makes a nice sealed wire connection. Better than pre-cut heat shrink — you can make whatever length you want.
Smart format for repair work
Great for keeping several sizes on hand without the bulk. Same quality as the large rolls — the adhesive seals perfectly every time.
