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
2 inch heat shrink tubing is the largest standard size made — a 50.8mm expanded bore that slides over the biggest cable bundles, large-diameter pipe and hose, and heavy industrial cable-assembly ends, then recovers to about 25.4mm (1 inch) on full heat. This is the 2:1 single-wall version: UL 224 polyolefin, flame-retardant, 600V, rated −55°C to +125°C. With no adhesive liner it is not waterproof — it is built for mechanical and abrasion protection, UV-resistant covering, and color-coding large bundles in dry-rated environments such as cable trays, MCC panel entries, and outdoor infrastructure. If you need a sealed, watertight sleeve over a 2 inch cable instead, choose the 3:1 dual-wall adhesive-lined version. Supplied as a 60ft bulk roll, cut to length.

High-volume UL listed polyolefin at an honest per-foot cost. The industry standard for color coding, bundling, and dry indoor electrical insulation.
Choose a size where the expanded diameter is 20–30% larger than your wire or bundle. Smaller tubes will slide on easier; slightly oversize is better than too tight.
Cut to length and thread onto the wire before making the splice. The tubing cannot pass over a crimped terminal — position it first, then complete the connection.
Use a heat gun at 90°C or higher for initial shrink, 120°C for full recovery. Work from the center outward. Avoid open flame — it scorches the tubing and creates uneven shrink.
Finished tubing should be tight with no bubbles or lifted edges. No adhesive will appear at the ends — this is single-wall tubing. Confirm even recovery across the full length.
Actual 2" tube at full expanded diameter (50.8mm) and after heat recovery. Use this as your fit reference before cutting.
Consolidates and protects the largest cable bundles in industrial facilities, data centers, and power distribution environments.
Provides large-diameter color identification on industrial wire harnesses for maintenance, commissioning, and future troubleshooting.
Identifies pipes, hoses, and conduits in process plants, mining operations, and heavy manufacturing facilities.
Applied at the point where large cable bundles enter panels and enclosures to distribute mechanical stress and prevent jacket wear.
Provides a clean finished end cap on cable tray bundles at termination points in industrial and commercial electrical installations.
Covers large cable assemblies in environments where abrasion, oil, and mechanical contact are present but submersion is not.

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.
Recovered diameter is approx. 1/2 of the expanded size shown · All sizes ship to USA & Canada
