Testing was conducted at SAE recommended assembly torque in hardened test blocks. The maximum pressure for any adapter or tube fitting must be lower of the chosen mating end types. Pressure ratings must be adjusted for any change in adapter material. All pressure ratings are shown in pounds per square inch (psi). Metric Compression Tube Fittings

HYDRAULIC HOSE AND COUPLINGS. From low-pressure to ultra-high pressure hose assemblies, and from application-specific systems to versatile fluid compatibility, the most productive hose systems start with the safest, most durable, and efficient industrial hoses, couplings, accessories, and equipment from Gates.

The chart below references nominal working pressure ratings for hydraulic steel tu classified as SAE J524, SAE J525, SAE J526 and SAE J356. These working pressures assume a 4:1 safety factor and have been calculated the standard formula P=S ( (D2-d2)/ (D2+d)). Please note the information provided is for reference only and should not be
