SAE J525 Hydraulic Tubing

Based on SAE J525, this chart indicates the nominal pressure ratings for tubing products. Based on the Lame formula with 12,500 PSI (86MPa) stress factors and a 4:1 design factor, these pressure ratings were derived. For the wall thicknesses shown in bold, SAE J533 recommends 37 degrees of single flaring for tubing with a normal wall thickness. Hydraulic systems perform satisfactorily at many different pressures based on a variety of factors. The values listed below should not be construed as standards or specifications, nor as minimum requirements. SAE J525 Hydraulic Tubing Equivalent Specifications
