Nice product at great price
Was wiring my car and had quite a few smaller wires to crimp and cover. This worked great — shrinks clean and consistent every time.

Helixal — Professional Heat Shrink Tubing
Helixal — Professional Heat Shrink Tubing
Helixal 2:1 heat shrink tubing — professional-grade insulation for everyday electrical work. UL listed, flame retardant, and available in the longest rolls on the market because serious work demands serious volume.
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 at 300–350°C in slow, consistent passes until the tube contracts uniformly around the wire with no loose sections.
Wire splice insulation, terminal and connector protection, panel wiring identification, and solder joint protection.
Production line harness assembly, repair of existing insulation, prototype wiring, and tool handle grip improvement.
Bundle and organize wire runs with a clean, uniform black finish. Identifies grouped circuits in complex panel builds.
Interior harness repairs, trailer wiring, body control module connections, and any application requiring general insulation.
Covers conductor insulation for circuit identification without additional tape. Consistent black finish across all 13 sizes.
Bulk stock for trade counters, repackaging in shorter lengths, and mixed-size kit assembly for maintenance contracts.

Perfect for bulk workshop use
Bought this for my automotive workshop and the 120ft roll is exactly what I needed. Shrinks consistently and cleanly every time. Much better value than small packs.
Professional finish every time
Clean black finish, no bubbles or wrinkles when applied correctly. UL listing is important for commercial electrical work — ticks that box too.
