Heat Shrink Tubing Assortment 30pc ALL76160

OVERVIEW

When you''re rewiring a vintage Type 1 or building a custom sand rail from the ground up, the biggest threat to your electrical system is often the environment itself. These Allstar Performance heat shrink tubes are the gold standard for sealing your connections against the vibration, moisture, and road grime that air-cooled Volkswagens encounter every day. Whether you''re repairing a brittle factory harness or installing a high-output alternator, this 30-piece assortment provides the mechanical strength and electrical insulation necessary to prevent shorts and corrosion. In the world of air-cooled engines where heat is always a factor, using a high-quality shrink tube ensures that your crimp or solder joints remain stable even when engine bay temperatures rise during a long summer cruise.

This specific kit is designed for the enthusiast who demands a clean, professional finish without the hassle of cutting long bulk rolls. Each piece is pre-cut to a convenient six-inch length, allowing you to slide them over your wires before terminating them for a sleek, OEM-style look. The 2:1 shrink ratio is incredibly forgiving, meaning the tubing will shrink to exactly half of its original diameter once heat is applied, conforming tightly around your wires and connectors to create a weatherproof barrier. Having this assortment on your workbench means you''ll always have the right size on hand for everything from small gauge sensor wires to thicker primary power leads, making it an essential addition to any VW restorer''s toolkit.

PRO TIPS

1. Use a Dedicated Heat Gun for a Uniform Seal

While many backyard mechanics reach for a cigarette lighter to shrink their tubing, I always recommend using a dedicated heat gun. A lighter produces an open flame that can easily soot the tubing or, worse, melt the insulation of the wire itself. A heat gun provides a broad, controllable flow of hot air that allows the tubing to shrink uniformly from all sides. Start at the center of the tube and work your way toward the edges to push out any trapped air, ensuring a moisture-tight seal that won''t fail when you''re out on the trail or in a heavy rainstorm.

2. The Slide-Before-Crimp Golden Rule

It sounds simple, but even the most seasoned builders have forgotten to slide the heat shrink onto the wire before crimping or soldering the terminal. Once that terminal is on, you can''t get the shrink tube over it. Make it a habit to cut your piece and slide it several inches away from the joint before applying heat to your solder. This prevents the ambient heat of the soldering iron from prematurely shrinking the tube while it is still sitting on the wire. If you''re working on a complex harness, use different sizes from this 30-piece kit to double-layer high-vibration areas for extra durability.

3. Account for Lengthwise Shrinkage

When planning your wiring, remember that heat shrink tubing doesn''t just shrink in diameter; it also loses a small percentage of its length during the heating process. This Allstar Performance kit comes with 6-inch lengths, which is plenty for most VW applications, but if you are covering a long splice, don''t cut the tube too short. Ensure you have at least a half-inch of overlap on the original wire insulation on both sides of the joint. This overlap provides the necessary strain relief, preventing the wire from flexing at the solder joint, which is the most common cause of electrical failure in high-vibration environments like a Dune Buggy or a stinger-exhaust Beetle.
