Product Snapshot

Product offerings include both low and medium pressure rubber hoses, nylon hoses (single & multilayer), thermoplastic tubes, and rubber gaskets.  Hoses can be custom blended and sized to meet OEM specifications.  In the automotive segment you will find Bates hoses spanning the entire length of the vehicle, from the rear liftgate to the engine compartment.  Our hose assemblies are an integral part of vehicle emission systems as they provide the means to circulate fuel and oil vapor thru various engine inlets and, with integrated leak detection sensors, alert the driver of emission leaks.
