Heath Sheath Aluminized Sleeving

Posted by James Broadway on Jun 3rd 2020

I first bought this product at the local auto parts store to insulate the drinking tube on my hydration pack I used for running. Not your usual use for these products, I know. The tube ran outside the pack and is exposed to sun, making the first couple mouthfuls of water pretty hot. After running this sheath over the clear rubber tubing, it got rid of almost all of the water heating. Maybe I could have used their Reflect-a-cool sheet to keep the heat from my back transferring into the water pouch too...
An added benefit is that it looks pretty cool and have been told a couple times that I look like an astronaut with this running over my shoulder.

Great product

This product is great and lasts a long time. Had one on a truck for over a year and velcro is still nice and tight.

I purchased this sleeve to cover my trans fluid lines on a 2000 F350 7.3 - Worked perfectly and should support keeping my trans temps down since the cooler is in front and the lines route next to the exhaust manifold. I would highly recommend.

We used a wide variety of DEI products, on my Stage 3 turbo install for my 2008 135i, from the Silicone Spray to the aluminum sleeves and both gold and aluminum tapes. So far they are working great after 1000 miles. Big fan of DEI!

I purchased this heat sheath for my AC lines that run close to the turbo and manifold on my car. The sheath is well made and should help increase the longevity of my AC lines.
