Design Engineering 010419 Heat Sheath 1" I.D. x 3ft Aluminized Sleeving for Ultimate Hi-Temp Protection

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.

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)

Using this on my 2013 chevy cruze to cover a coolant line (that’s right next to the engine block) from being warped. So far after a few months, it’s holding up pretty good!

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.

Tad bit large

I got these for my transmission cooler metal lines that run right next to my new long tube headers to keep the lines/trans fluid as cool as possible. I used these because I had the transmission out for a rebuild and could slide these over the lines. ATTN: wear gloves when installing these because there is fiberglass in these and it will get all stuck in your fingers and annoy you for days (don’t ask how I know). These weren’t as flexible and bendable as I was hoping to go around the prebent metal trans lines and as you do flex and bend the product the aluminum foil exterior starts to tear and crack. Overall I hope this helps to protect the trans lines and keeps them cooler.

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
