3/8″ WIDE HIGH HEAT TAPE

3/8″ Wide High Heat Tape – Narrow Profile Polyimide Tape for Precise Harness and Connector Heat Protection

The 3/8″ Wide High Heat Tape is a narrow-profile polyimide high-temperature tape for precision thermal protection, connector body insulation, and targeted heat shielding in professional motorsport wiring builds. At 3/8 inch (9.5mm) wide, this tape provides the fine control needed for wrapping individual conductors, insulating connector bodies, and covering small-diameter branch terminations in tight harness locations across race cars and performance vehicles in Norway, Sweden, and Denmark.

Narrow Width, Precise Application

The 3/8-inch width is the most precise format in the high heat tape range, offering the builder control that the wider 1/2″ and 1″ tapes cannot provide in tight spaces. It is particularly well suited to wrapping individual sensor wires near exhaust components, insulating the bodies of small connectors in engine bay locations, sealing heat shrink overlap joints on single conductors, and covering small harness branches in congested areas around the engine, turbocharger, or exhaust manifold where a wider tape would be unwieldy or difficult to apply cleanly.
