What is the best way to apply this heat shrink tubing?

You'll need a heat gun to apply this tubing. The manufacturer recommends applying heat between 120°F and 180°F for optimal shrinking and a secure, water-tight seal.

Can this tubing be used near exhaust components?

No, you should not apply this tubing directly to exhaust components. While it has a high operating temperature range, direct contact with exhaust parts can exceed its limits.

What does the 3:1 shrink ratio mean?

A 3:1 shrink ratio means the tubing will shrink down to one-third of its original diameter when heated. This allows it to form a very tight and secure fit around wires and connections.

Product Details

When you're working on wiring, especially in the engine bay where things can get hot and messy, you need a reliable way to protect your connections. This Hi-Temp Shrink Tube from DEI is a solid option for insulating wires, splices, and terminals, giving you a clean, professional look that holds up.

This tubing has a 3:1 shrink ratio, meaning it shrinks down to one-third of its original diameter when heated, creating a snug, water-tight seal. It's made from flexible polyolefin that stays pliable even after shrinking, and it meets military specifications for electrical insulation and protection against dirt, dust, and solvents. The operating temperature range is -67°F to 275°F, with a notable ability to handle up to 394°F for short durations, making it suitable for many under-hood applications. Just apply heat with a heat gun between 120°F and 180°F to get a secure fit.

This 50-foot spool gives you plenty to work with for multiple projects. It's a great alternative to messy electrical tape or zip ties when you need a durable, long-lasting seal.
