The cooler comes as a complete kit with extra transmission hose fittings clamps and zip ties. All three of these coolers have an effective cooling area right around 75 square inches so their cooling performance is similar.
Choosing a proper size is based on a few factors. For example if a hydraulic system has a continuous input power of 100kw and its 80 percent efficient then 80kw is available at the output to do useful work and 20kw is converted to heat.
