Composite hose assemblies are used in any application that benefits from a flexible, safe and chemically resistant hose.  

Flexible: Composite assemblies are more flexible than almost any other hose types. When composite hose is moved or bent, the layers slide over each other, making the hose very flexible and providing for small bend radii.

Safe: Composite hoses provide some “fail safe“ characteristics. The construction consists of layers of tubes and film. For a leak to occur, liquid must serpentine its way through the many layers until it reaches the outer cover. Once the liquid reaches the outer cover, small drops will form along the seam line indicating that a leak is occurring. The end fittings are specifically designed to reduce the chance of a fitting blowing off the end of the hose. The fitting’s spiral shank screws into the composite hose before swaging, creating a more secure end fitting connection.

Chemical Resistance: Composite hoses are most commonly used in the transfer of chemicals. The bore of the hose can be made from polypropylene, Teflon and Nylon, compatible with most common chemicals.
