Description
The Mishimoto Heat Defense Tape, part number MMGRT-215, is a gold, self-adhering heat shield tape built from highly reflective metalized polyimide film laminated to glass cloth — the same reflective film technology used by the space industry to protect sensitive instruments from extreme heat. Rated to withstand up to 675°F of radiant heat, this tape is engineered to shield wiring, hoses, and other sensitive engine components from damaging heat exposure.
As part of Mishimoto’s Fabrication lineup, Heat Defense Tape gives builders and DIY mechanics a straightforward way to add heat protection anywhere it’s needed under the hood. The metalized polyimide film reflects radiant heat away from delicate components, while the glass cloth backing and high-temperature laminating adhesive keep the tape durable and stable in demanding engine bay environments. A high-temperature pressure-sensitive adhesive lets it self-adhere directly to surfaces, and an easy-to-remove protective backing keeps the adhesive clean and ready to apply until you’re set to install it. Whether you’re wrapping a wiring harness, hose, or another sensitive part during a custom fabrication build, this tape offers a simple stick-on solution for heat management.
Vehicle Applications
Mishimoto Heat Defense Tape is a universal fabrication product and is not restricted to a specific make or model — it can be applied wherever heat protection is needed in an engine bay, making it a flexible addition to custom builds, fabrication projects, and general heat-management applications across vehicles.
