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
1-1/2 inch heat shrink tubing is designed for industrial cable protection sleeves, large-bundle color-coding in process plants and data centers, conduit termination finishing, and the largest cable assemblies in commercial and industrial electrical work. Typical applications include sleeving over multi-conductor bundles at switchgear entries, covering cable tray exits through fire-rated walls, and providing abrasion protection on OD-critical cable assemblies where 38mm bore is the minimum workable size. At 38mm expanded diameter, this tube slides freely over very large cables and bundles and recovers to approximately 19.0mm. The 2:1 single-wall construction, qualified to UL 224, is the right specification for abrasion protection, color coding, and mechanical strain relief in dry industrial environments. When the sleeve must provide a water-resistant barrier at a cable penetration through an outdoor enclosure or wet-rated panel, the 3:1 dual-wall adhesive version is the appropriate choice. The 60ft roll is a practical stocking quantity for facility maintenance teams and industrial contractors who need large-diameter sleeving available on-demand without the cost of special-order quantities.

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 1-1/2" tube at full expanded diameter (38mm) 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
