DEI Hi-Temp Shrink Tube 12mm x 200ft Spool - Black

When you're working on wiring in the engine bay, especially around heat sources, you need protection that can handle the temperature. This Hi-Temp Shrink Tube from DEI is designed for those demanding situations. It's a flexible polyolefin tubing that offers excellent electrical insulation and shields your wires, splices, and terminals from dirt, dust, and solvents.

What's really useful here is the 3:1 shrink ratio. That means this tubing shrinks down to one-third of its original diameter when heated, creating a snug, water-tight seal around your connections without changing its length. It meets military spec DTL-23053/5C, which tells you it's built to last in tough conditions, with an operating temperature range from -67°F to 275°F. Just apply heat with a heat gun between 120°F and 180°F to get that secure seal.

This is a 200-foot spool, so you'll have plenty to work with for multiple projects or longer runs. Just remember, while it's high-temperature rated, don't apply it directly to exhaust components.
