The pressure standards are for fluid power connections made of low carbon steel. Port connections may have a higher or lower strength. Some manufacturers products may not meet SAE specifications, in which case the product may have a lower pressure rating. Some manufacturers products may exceed SAE specifications, in which case the product may have a higher pressure rating. THE MAXIMUM DYNAMIC WORKING PRESSURE OF THE ENTIRE ASSEMBLY IS THE LESSER OF THE HOSE, TUBE, ENDS, ADAPTERS AND COUPLINGS USED IN THE ASSEMBLY.
