hydraulic hose pressure rating chart

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

10/19 · Max. Operating Pressure: 375 to 1,500 psi. Min. Bend Radius: 3” to 10”. Usage: General use as a low-pressure hydraulic hose, including antifreeze and hydraulic oil. SAE 100R4. Reinforcement: Single or more braid textile with spiral wire. Diameter Range: 3/4″ to 4”. Max. Operating Pressure: 35 to 300 psi.

Pressure rating— A hose must be chosen with a maximum working pressure (WP) rating that is at or preferably above the normal maximum hydraulic 

Constant Pressure Spiral Hose are designed to be easily identifiable by pressure rating for safe replacement. 5. NEW LOW TEMP HOSE RATED TO -70°F Key Products Arctic Hose High-pressure hydraulic hose used in construction, forestry, surface mining, oil and gas, waste handling, utilities and other applications where lower temperature can impact

A nomograph is essentially a hose sizes chart. Consider your correct hose I.D., desired flow rate, and recommended flow velocity. If you know any of these two values, you can determine the third using the nomograph chart below. Pick your two known values. Lay a straight edge, intersecting those two values. Intersection on the third vertical

All Parker hydraulic hoses offer a 4:1 safety factor, which means if the hose is rated at 5,000 psi working pressure, the burst pressure will be 20,000 psi. Keep in mind, the lowest rated component gives the overall assembly's working pressure rating. Just because a hose assembly is rated to 5,000 psi doesn't mean all of the adapters are too.
