What is the automotive industries definition of a hard line of a Hard Line?

I have my 6.0 in the shop now. It's been diagnosed with needing an Oil Cooler, EGR Cooler, EGR, and a turbo rebuild and flush. So far the bill has pegged at $4,200. I have an extended warranty that covers some very specific items but is also vague in others. For instance, it does not specifically cover the EGR Cooler, however it covers something called "hard Lines." I'm supposing hard lines are metal lines that carry fluid from one point to the other. I've been arguing with the warranty company that the EGR Cooler is in fact a hard line. It's static in nature, does not have any internal moving parts and is used to move coolant from A to B. Just because it's function is to cool the coolant is irrelevant. They of course disagree and say that it's specifically an EGR Cooler not a hard line. It's kind of a "all poodles are dogs but not all dogs are poodles" kind of thing.

I'm interested if anyone knows of an industrial definition of a hard line and if you think I'm right or wrong...

No, the egr cooler is not a hard line. Sorry, most aftermarket warranty companies exclude this part since it is such a common failure part. I'm surprised they don't exclude the oil cooler too.

It pays to read the exclusions on your extended warranty BEFORE you sign on the dotted line. Most of them are a complete ripoff.

I agree. Basically I bought a gas engine warranty for a diesel. And most warranties don't list exclusions, just parts they cover. Then they tell you if it's not in the warranty it's not covered.
