Beschreibung
Zusammenfassung:	A flexible low permeability hose (10) for providing an impermeable length of tube to transfer fluids that is flexible. The flexible low permeability hose (10) generally includes a first layer (20) and a second layer (40) surrounding the first layer (20), wherein a first adhesive (30) secures the second layer (40) to the first layer (20). The first layer (20) is comprised of a material not adversely affected by coolants (e.g. perfluorocarbon fluids) such as but not limited to polyethylene. The second layer (40) is comprised of a material that is impermeable to coolants and gases (e.g. ether based or ester based polyurethane material) to prevent the escape of the coolant from the hose and to prevent the entry of air into the coolant through permeation. An additional third layer (60) may be secured about the second layer (40) with a second adhesive (50) to provide protection to the second layer (e.g. fire protection, fluid exposure).
