What is the shrink ratio of this tubing?

This Hi-Temp Shrink Tube has a 3:1 shrink ratio. This means it will shrink down to one-third of its original diameter when heated, creating a very snug and protective seal around wires and connectors.

What temperature range can this tubing withstand?

The tubing is designed to operate in a wide temperature range, from -67°F up to 275°F. It also stays flexible throughout this range, which is important for wiring that might experience movement or vibration.

What is needed to install this shrink tube?

You will need a heat gun to properly shrink the tubing. The manufacturer recommends applying heat at temperatures between 120°F and 180°F for optimal results and a secure, water-tight seal.

Product Details

DEI is known for making quality thermal management products for automotive applications. This Hi-Temp Shrink Tube is a great example, offering a robust solution for protecting electrical connections and wiring. It's a military-spec flexible polyolefin tubing that shields your wires from dirt, dust, solvents, and other contaminants, while also providing important strain relief.

What's really useful about this tubing is its 3:1 shrink ratio. You can easily fit it over wires and connectors, and then with a heat gun, it shrinks down to one-third of its original size. This creates a snug, water-tight seal without changing the tube's length, ensuring a clean and protected finish. It meets the material functional properties of Military Spec DTL-23053/5C, and it stays flexible even in a wide operating temperature range from -67°F to 275°F. You'll want to apply heat between 120°F and 180°F using a heat gun for the best results.

This 500-foot spool gives you plenty of material for a variety of projects, whether you're insulating wires, working on splices, or securing terminals. It's a well-built part that will hold up well in demanding engine bay environments.
