Composite Hoses

Two Industry Leading Brands: United Flexible & Willcox®

Our composite hose can handle hydrocarbon, chemical and cryogenic fluids: utilizing multiple tight-wound component layers that create a very long and complex course for fluids. The unique manufacturing process assures the proper gauge and pitch of the inner and outer wires at all times. Our composite hose is rated for both positive pressure and full vacuum, it will not kink with ease of daily handling it will provide excellent service life and performance.

All of our mandrel manufactured composite hoses are built with many multiple wraps of both polar and non-polar thermoplastic films that contain the fluids and vapors inside the hose wall. The barrier layer in all our standard oil and chemical hoses prevents permeation by both polar fluids (like methanol) and non-polar liquids (like gasoline) from escaping the hose. The hose wall is then reinforced with bulk woven fabrics that help protect the films in the hose wall from mechanical damage. This provides you a composite hose with superb structure and heavy duty cover layers that do not deteriorate due to ozone, UV, oil or chemical attack; that maintains maximum strength, flexibility and durability.

Assemblies are also available with specified electrical resistance, semi-conductive or non-conductive properties. But the vast majority of hose assemblies are electrically conductive and an ohm reading of less than 10 ohms.
