Helixal — Professional Heat Shrink Tubing
Helixal 3:1 ratio heat shrink tubing with an adhesive lined dual wall construction. The inner liner melts and seals every gap — creating a joint that water, fuel, and corrosion cannot reach.
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.
Bilge pump wiring, navigation light terminals, battery cable ends — wherever saltwater or moisture reaches the connection.
Engine bay harness repairs, trailer wiring connectors, battery terminal protection, under-hood sensor leads and looms.
Control panel wiring, outdoor cable terminations, mechanical strain relief, and corrosive environment protection.
Adhesive liner seals out moisture and corrosion — the leading cause of terminal failure. Heat until adhesive flows from both ends.
UV-resistant outer sleeve handles long-term sun and weather exposure without cracking or becoming brittle.
Built to MIL-DTL-23053/4 specification — the same standard used in aerospace, defense, and naval applications.
High quality and amazing value for the price
I'll never buy individual bags of heat shrink tubing again. This is very high quality with a shrink ratio that is truly amazing. I wonder if I'll be able to use this entire roll in 10 years!
Solid waterproof bond
It's tough, flexible, and the adhesive flows nicely to create a professional-looking finish and a solid waterproof bond.
I LIKE THIS!
I solder, and heat shrink, all of my automotive electrical connections. This is a great product, and I can cut it to any length. The price is great, and the shipping was fast!
