Design Engineering Heat Sheath – 3/4" Inner Diameter x 3ft – Aluminized Sleeving for Extreme Heat Protection on Cables, Spark Plug Wires, and Fuel Lines

I used this on the wires that go to the starter on a 2008 Jeep Wrangler. The insulation on the wire that energizes the starter solenoid had melted even with the factory starter heat shield in place. This Jeep has a design problem because the catalytic converters are very close to the starter. This heat shield work great for this application and solved the problem.

I bought this to help with a vapor lock issue on my Charger.. Not only did this completely fix the problem, but the product was simple to install and very well constructed,, i would for sure buy again without hesitation and recommend to others.

works good for keeping heat away form fuel lines.

I bought this to go around my transmission lines but to my surprise it's all sewed together, which is fine but it's hard work to pull lines and slide this on. I was thinking it was velcro and I could just wrap my lines.

worked as descibed

I needed heat protection for a couple of 16 awg gxl lines I ran to power rock lighting under my off-roader since the wires route past the exhaust man and the catalytic converter. I mean, yes the wiring is a good 6" away, but why take a chance since melted wires will result in a short which can result in fire. This sleeve slid over the wire loom with some maneuvering since I ordered the 1/2" heat sheath and the loom was 1/4", but that was my bad. In the end, this is doing just what I wanted, protecting the wiring from extreme temperatures in the engine bay. Now I haven't taken the vehicle on a good long shake-out run yet, but I will and if there are problems, I will update this review.

I used a 3/4" x 3 feet sheath. It was used around a 0awg (8.25mm) start cable that was installed in close proximity to the catalytic converter. The starter solenoid wires were double shielded, so I folded the 3/4" sleeve and used stainless steel ties to hold the folded sleeve in place around the 0awg cable.+ Seems to be av good quality materials.+ Good stitching.- Large flap with company logo(Understand logo solution - removed flap for cleaner install)

So far so good - it's heavy cloth with reflective coating. The coating is bonded well - doesn't flake off or separate. Just a few things - note in the photos how frayed and sloppy the material and stitching is in what you receive versus what they show in the ad photos, all nice and clean. Very sloppy. Will it last? Bummer. Also, it is sewn with a rather large flap of extra material on the side for the length of the tube making it appear almost twice as wide. They should use a sewer that allows the tube to be all that is exposed rather than all that extra material. But Ill look past that. .Also not sure why it needs a huge name tag on it but I'll trim that off. Will check back in and edit once it has had a chance to protect the wiring near the exhaust manifolds. Hoping it lasts out here in the AZ oven.

In DEI packaging. Real product. Worked great

Large enough diameter to fit most fuel lines while accommodating bends and fittings. Simply disconnected line at carb, slid the sheath on, cut to length (Mercruiser V6).

Used to keep parts of a wiring harness and fuel lines protected in high temperature areas. Works as it should and easy enough to work with.

Wish it was a little longer. No more burnt up starter wire.

Easy to use had some wires the melting after being to close to the exhaust. But the wire bundle in the sealed tube and no issues with wires melting
