Hydraulic systems are vital to the operation of industrial equipment and heavy machinery. They are integral from the manufacturing of parts to systems that power agricultural combines. In any application, hydraulic hoses can fail due to selection of the wrong hose over pressurizing, improper installation of fittings and more. Yet a commonly overlooked potential hazard is extreme temperatures. Both high and low temperatures can a have significant effect on the efficiency, performance, and safety of a hydraulic system.
