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.

Look, when you need this stuff, it's worth the price. It works, and does the job of protecting the wires or hoses it's supposed to. I think it's a bit expensive, but you buy this for reliable protection, and that's what you get. Sure, there are off brand stuff similar, but I paid for the peace of mind DEI provides. Used to protect 1/0 starter cable on my LS truck motor from header heat.
