Heat shrink 60 mm

60 mm heat shrink tubing is designed to protect and repair cables and larger wire assemblies. The product with 60 mm inner diameter and 1 meter length provides a large, durable sleeve for insulating and bundling sizable cables or connectors. Made from polyolefin, it shrinks securely over the joined area when heated, helping to prevent insulation damage and corrosion while offering good electrical insulation for various projects.

This lineup includes a wide spectrum of diameters and lengths, from 3–6 mm tiny tubes to 60 mm sleeves, plus multi‑pack sets. For example, there are sets offering 3–4–5–6 mm pieces in multiple counts, and larger packs with dozens to hundreds of pieces in assorted sizes and colors. Such variety lets you select exact dimensions for different cables, sockets, or repairs without buying multiple separate kits.

The shrinkage ratio describes how much the tubing will reduce in diameter when heated. A 2:1 ratio means the tube will shrink to half of its supplied diameter. This helps you plan for tight fits on wires or connectors, since a larger diameter sleeve can shrink down to a compact, secure insulation around a cable bundle or splice, improving protection and organization.

First slide the tube over the cable section you want to protect, then apply heat evenly with a heat gun or lighter until it contracts snugly around the cable. In practice, some kits come with multiple sizes and include guidance on cutting; use scissors for clean edges and ensure you do not overheat to avoid damage. Allow the sleeve to cool before testing the insulated joint for any movement.

Look for polyolefin tubing for durability and flexibility, with flame retardant characteristics and good dielectric strength for electrical insulation. In the detailed specs, you may find tensile strength around 10 MPa and dielectric strength around 15 kV/mm, which indicate robust resistance to mechanical stress and electrical leakage. Temperature tolerance often ranges from about 55°C to 125°C, ensuring performance in various environments.

If your project involves several cable sizes, a large multi‑size kit is ideal—for example, an 164‑piece set offering eight sizes and multiple colors provides breadth for various repairs and installations. If you only need a single size, choose a smaller pack that includes that specific inner diameter and a manageable length. Having a few color options can also help in quickly identifying different cable runs.
