Will this be a pressure wash hose or a foam brush hose or a solution hose? Depending on what the hose will be used for will be the first most important consideration in the selection of the hose assembly components. Pressure falls into two general ranges, high pressure and low pressure. There is really no advantage to using a 3000 psi rated hose where the normal operating pressure will be 60 - 75 psi. As is also the case with temperature. One should always use a temperature rated hose when hot liquids or gases are to be transferred. In these cases using a hose rated higher than the intended service range is unnecessary and a waste of money. The higher rated hose generally costing more. On the other hand one would definitely not want to use a hose rated for 200 psi where 1200 psi pressures are expected to be encountered.
