The inner liner tube is surrounded by a plurality of thermally insulating layers and a braided or woven reinforcement layer. Such layers are then encapsulated by at least one radially rubber cover layer. A hose assembly end fitting arrangement is also provided in which an end fitting is crimped to a hose end via a two component end fitting and a portion of the end fitting is surrounded by rubber.
