How to Keep Critical IBC Flexible Ducts from Failing
IBC systems rely on ducting to get the required air into and out of the die. Multiple pipe dies requires multiple flexible hoses that are subject to extreme heat. High temperature and strength hose gets this done provided you do not exceed the bend radius rating.
The excessive bend radius shown here will cause premature failure of the hose. Once the side wall breaks, layflat control will quickly deteriorate.

Click here for more details on how this hose provides increased life and better reliability.
