SAE J2551-3-2020 PDF

Scope: Purpose These recommended practices provide general recommendations for designing and fabricating metallic tubes and tube assemblies for fluid power applications utilizing commonly available manufacturing methods and general guidelines for tube selection and application. Field of Application These recommended practices are intended for general application and hydraulic systems on industrial equipment and commercial products. Aircraft and Aerospace applications were not considered during the preparation of this document. Since many factors influence the pressure at which a hydraulic system will or will not perform satisfactorily@ these recommended practices should not be construed as guaranteed minimums. For any application@ it is recommended that sufficient testing be conducted and reviewed by both the user and manufacturer to ensure that required performance levels are met. For use of these recommended practices and connectors in conditions outside the pressure and temperature of limits specified@ the manufacturers must be consulted. Both metric and inch tubing should be considered to accommodate hydraulic system design requirements. In the past@ these requirements have been met predominantly with inch tubing; for new designs@ metric tubing should be considered.
