Insulation Heat Shielded Fire Thermo Armor Fire Sleeve Silicone Coated Fiberglass Heat Protection for Automotive Hose Lines & Electrical Wiring-（Black 1/2"ID x5FT）

I bought the 1 inch inside diameter and it is able to stretch to a little over 1.5 inches. It snaps right back into the smaller size once it is around the object which makes it very useful for going over fittings. It can be cut with normal scissors, but you need a little force, a razor or very sharp shears works better. I took loose pieces of the fiberglass and held it under a butane torch and they acted as typical fiberglass and did not catch fire, but did eventually melt. Great product.

My exhaust pipe for the generator on my Toyota Dolphin motorhome was rattling against the frame and we used this to slide over it. It stretched good enough to put a second piece over the first piece and this allowed a nice cushion between the tail pipe and frame and now we are noise free!

If you have fuel lines or other things under a very hot hood like we did. A V8 crammed into a small old classic with headers. This does the trick to prevent damage or fuel flashing from heat.

Used it to cover a generator exhaust extension out of my garage and keep the heat down. Well..... its does that but filled my garage with rubber smoke. It smokes a lot. I'll give it 4 stars for doing what it claimed to do, keeping the heat contained, but the smoke is a deal breaker for me and I'll be removing it and replacing it with kevlar header wrap.

I wasn’t holding out much hope as to this product’s claim of being able to withstand a constant 800 degrees and up to 1200 momentarily. I decided to test it with a heat gun that I own. The gun will only go up to 1100 degrees, but this product held up fine without any evidence of outgassing, smoking or catching on fire.Considering the price of ASTM/UL rated equivalents being in the 3X cost range, it was worth a try. I will report back if I encounter issues with it after installing.

looks great. i don't see any issues that should arise.

works perfectly on my propane van furnace exhaust

The ignition wire at my water heater often burns out. I bought this cover and wrapped it around the ignition wire and it never burns out again. It's great.
