Plumbing – What temperature are faucet feed lines rated for? (don’t want them to leach into potable fluid)

plumbing

I am planning on using the flexible faucet feed lines for a project I am working on. (they have a metallic outside and I suspect vinyl or plastic interior)

The temperature of the fluid that I will be running though it (maple sap) will be around 100F to 180F – but I don't know yet. I am building a preheater out of copper tube and need a way to connect two parts that are fixed but must be able to disconnect

I don't want the part to fail or break down and I do not want the material to leach into the fluid.

Are these feed lines acceptable for temps to 180F?

Is there another alternative that allows flexibility and easy connect/disconnect on one side of the part?

The tubing should have a stamp on the side that says what temperature range it can handle.
