I've never heard anything like that?
The real thing you need to pay attention to about hoses is the anti-static factor. You'll get tired of getting shocked real quick.
The more cost-effective way to buy a 36mm hose is to get the Craftsman cleaning set. It gets you the hose itself, the wands and several brushes, and a Systainer to store it in. (or sell off, and recover some of the cost)
