This information report provides general information for installing and tightening fluid conductors and connectors. Following these guidelines, with the consistent proper use of torque wrenches, tightening procedures and correct torque levels will result in diminishing leaks and improving service life by avoiding hose twisting, tube binding, false torques and improper joint closures. Since many factors influence the pressure at which a hydraulic system will or will not perform satisfactorily, this report should not be used as a "standard" nor a "specification" and the values shown should not be construed as guaranteed" minimums, maximums or absolutes.
This document is an information report to help users by gathering available information from the various connector standards and publishing the information in one source for easy retrieval and applied common usage. This information report is primarily intended for mobile/stationary industrial equipment applications. Aircraft, Automotive and Aerospace applications were not considered during the preparation of this document.
When assembly procedure and torque level discrepancies between this document and associated connector specifications occur, the current connector specifications shall take precedence.
This change is required to remove ambiguity, provide common installation instructions for all SAE STO port connections and improve the instructions by providing information to better protect the back-up washer during installation by requiring the assembler to position the locknut in the correct position to prevent washer damage and deformation. If the use of these instructions is properly observed, recognized and used by the user community, the result will be a considerable overall improvement throughout the fluid carrier industry concerning the overall reduction of leaks.
Projects are underway to remove ORB port connector installation instructions from J514, J1926 and J1453. This document should go to publishing prior to the changes to J514, J1926 and J1453.
