Shield Critical Components from Extreme Heat

Modern vehicles and performance builds generate intense under-hood temperatures that can weaken wiring, damage fuel and fluid lines, and cause heat-soak issues that affect reliability. Thermaflect Tube provides an easy, effective way to protect sensitive lines and harnesses from radiant heat in tight engine bays, turbo systems, EV powertrains, and heavy-duty applications.

Fast, Simple Installation

The self-closing wrap design installs quickly without removing fittings or connectors. Thermaflect Tube conforms easily around bends, junctions, and tight spaces for a clean, professional fit on custom builds, factory systems, and retrofit installations.

Reliable Protection for High-Heat Builds

When heat threatens critical components, Thermaflect Tube delivers proven thermal protection to help your vehicle run stronger, last longer, and perform at its best — no matter the driving conditions.

FAQ

How do I install Thermaflect Tube?

Thermaflect Tube uses a self-closing wrap design. Measure the length you need, cut it to size, and wrap it around the line or wire — then press it closed. No disconnecting parts or special tools required.

Where should I use Thermaflect Tube?

Use it anywhere heat threatens component life — near exhaust systems, turbo pipes, catalytic converters, battery systems, power inverters, fuel lines, and wiring harnesses.
