Every hydraulic hose that is used on equipment shall have the hydraulic hose manufacturer's rated pressure in pounds per square inch (psi) permanently affixed on the outer surface of the hose and repeated at least every two feet. Every hose installed on an automatic displacement hydraulic system shall either (i) have a four-to-one safety factor based on the ratio between minimum burst pressure and the setting of the hydraulic unloading system, such as a relief valve, or (ii) meet the minimum hose pressure requirements set by the hydraulic equipment manufacturer per the applicable hose standards for each type of equipment. No hydraulic hose shall be used in an application where the hydraulic unloading system is set higher than the hose's rated pressure.
