Heatshield Products(204011) 3/8" ID x 10' Hot Rod Sleeve Roll

Used this for my push button wiring that runs to my starter right next to the headers and it does a great job

I like the design and looks. Was easy to cut and install on a rubber fuel line that is near a header. The issue I have is it only comes with two shrink sleeves. Then you have to buy those separately at an exorbitant price with exorbitant shipping. Also be warned if you have the 1/2 inch sleeve you have to buy the 3/4 inch shrink sleeve. I purchased 1/2 inch thinking it matched those protective sleeve only to discover it’s too small. Discovered this three days after I could return them so I shelled out $29.71 for 8 heat shrink sleeves I can’t use and I honestly don’t want to spend another $30 for 6 of the larger size but am going to have to.

to size but will stretch some ,,,,, very good product ,,i always order bigger to dissipate the heat better

Very nice tight weave product. Installed easily over brass fittings in fuel lines and appears clean and neat. Supplied with two pieces of manufacture branded heat shrink. For the included length of wrap and cost of kit several pieces of heat shrink would have been very helpful.

One layer of this stuff doesn't do much as it's fire proof but not exactly a high efficiency insulator (I tested). I installed as two layers wherever possible, which is difficult on longer runs but easy on short. Be sure to cut it long enough so it doesn't pull back and waste your nice shrink-wrap termination. It only comes with two short pieces of shrink wrap, so be prepared to buy more and it's not inexpensive. Anyway, as two layers it does ok, but it's expensive and stingy on the enclosed shrink wrap so I give it 4 stars instead of 5.

Used this on my miata power wire. The battery is in the back of the car and the power wire runs to the front right next to the exhaust. I feel a lot safer with this stuff around the wire to make sure it doesn't melt. The reason for 4 starts is I'm not a huge fan of the heat shrink that comes with this. Because my wire was a little smaller than recommended I ended up using some zip ties and some slightly smaller heat shrink. If the heat shrink was a little longer it might have worked. It's pretty short for such a long piece of heat wrap.

This is high quality stuff, and the size is perfect for the smaller tubes, it stretches a little so you can go to 5/8 and probably 3/4 but I wouldn't stretch it too much or you'll lose the shielding properties. I used it on my fuel lines going from the fuel pump to the carburetor and the under hood fuel line going to the fuel pump. I hope it can help with the vapor locking. I like the heat shrinking end pieces but I don't know if they are better than stainless or plastic zip ties, but I used them and they look nice.

Use 1/2" for a 3/8" fuel hose. Product is well made. I used on custom fuel setup for my Subaru. I honestly don't know if it can handle the heat rating, but engines don't get to 1100 degrees anyways, maybe a turbo or exhaust pipe will. I have done a different Subaru with custom routed fuel lines under the manifold without heatshields and I never had a problem with those. I feel that these will add more security to the hoses. Makes the fuel lines look cool too.*The headshield works like a Chinese finger trap, you need to push from the bottom and the top will loosen up to slide the hose in. Not hard at all once you get the hang of it.
