O'Brien tubing bundles provide the most economical and dependable solution for permanent installations. O'Brien tubing bundles can also be used to provide a heated flexible hook-up between moving parts of machinery or for product dispensing and unloading. Flexible applications with factory finished ends are often referred to as heated hose.

Parallel tube construction induces less unrelieved stress in the process tubes than cabled bundles and has less likelihood of creating surface scratches on the tubes.  Insulation must be kept dry at all times including construction.  Heat shrink end seal boots should be used to seal all bundle ends.  PVC coated communications wires should be eliminated and Teflon used in its place.  Polyurethane jacket contains no chlorides that could contribute to stress corrosion cracking and has a much better weather and UV resistance than PVC.
