Cat hoses are designed to route liquids and gases through machine systems. These hoses are fabricated from superior materials to withstand application specific pressures, vibration tolerances and flow requirements for Cat heavy-duty equipment. Cat hydraulic hose and couplings are subjected to the most rigorous testing processes in the industry. Every Cat hose and coupling combination is tested as a system to ensure a perfect fit that yields maximum safety and dependability. Hose construction shall consist of a seamless, synthetic rubber inner tube, suitable textile reinforcement, and an oil, fuel, and weather resistant synthetic rubber outer cover or textile braided cover. The inner tube may be backed by an additional elastomeric materia
