127-Piece Heat Shrink Tubing Assortment — 7 Sizes for Every Job
Keep your wiring neat, protected, and professional-looking with this comprehensive 127-piece heat shrink tubing kit. Made from high-quality 2:1 ratio polyolefin, each tube shrinks to half its original diameter when heated, forming a snug, secure sleeve around wires, cables, connectors, and terminals. Perfect for automotive wiring, DIY electronics, marine projects, and home repairs.
The kit includes seven different internal diameters — from 2.0 mm all the way up to 13.0 mm — so you always have the right size on hand. The high expansion ratio makes it easy to slide the tubing over connectors and irregular shapes before shrinking, saving time and eliminating the need to completely disassemble cable runs.
Made in Mainland China.

Frequently Asked Questions
Q: What heat source can I use to shrink this polyolefin tubing?
A: A standard heat gun set to around 90–120 °C (195–250 °F) is ideal. You can also carefully use a lighter or matches for quick field repairs, though a heat gun gives the most even, controlled shrink. Avoid open flame where possible for a clean result.
Q: What is the minimum wire diameter this kit covers?
A: The smallest tube in the kit has a supplied internal diameter of 2.0 mm, which shrinks down to approximately 1.0 mm — suitable for thin signal wires, thermocouple leads, and 24–30 AWG conductors.
Q: Is this heat shrink tubing waterproof?
A: This standard 2:1 polyolefin tubing provides excellent moisture resistance and is suitable for most automotive and outdoor applications, but it does not contain an inner adhesive lining. For fully waterproof/submersible connections, consider adhesive-lined (3:1) heat shrink tubing.
Q: Can these tubes be used on car wiring and automotive harnesses?
A: Yes — this kit is specifically well-suited for automotive cable sleeving, wire splice protection, and harness repair. The polyolefin material withstands the temperatures, vibration, and fluid exposure typical of engine bays and interior wiring.
