anyone tested this against flame or harsh heat?

After fitting it to a bolt for testing I put direct flame on it from a lighter. It's certainly resistant, because it would melt and bubble with flame on it, but once removed from flame the heat shrink was not on fire.

What is operating temprature limits after application? I want to use it in an oven with tc wires, high temps reaching 350 degrees.

I don't know the answer. I am using the product for sound cables and I think that they are very reliable but I do not know if it can reach. In this case it is better to ask the manufacturer

Will this kit work for 0 gauge wire and 8 gauge wire

Hello, the working wire range of this heat shrink tubing kit is 18 AWG- 1 AWG.
