DEI Hi-Temp Shrink Tube 12mm x 4ft - Black

This is the DEI Hi-Temp Shrink Tube, a 12mm wide, 4-foot long piece of black tubing. It's designed to give you a clean, professional finish when you're working on electrical connections, wire splices, or just need to insulate individual wires. Think of it as a tougher, more durable alternative to electrical tape or zip ties for protecting your wiring.

What makes this stuff useful is its 3:1 shrink ratio. That means when you apply heat, it shrinks down to one-third of its original diameter, creating a really snug, water-tight seal around whatever you're protecting. It stays flexible even when shrunk and can handle temperatures from -67°F up to 275°F, with short bursts up to 394°F. It meets military spec DTL-23053/5C, which is a good indicator of its reliability and performance in tough conditions. You'll need a heat gun to apply it, typically between 120°F and 180°F.
