This SAE standard specifies uniform methods for the testing of threadless connections for hydraulic fluid power applications. These connections are intended for general application and hydraulic systems on industrial equipment and commercial products. These connections shall be capable of providing leak proof connections in hydraulic systems operating from 95 kPa vacuum to working pressures specified by the manufacturer. Since many factors influence the pressure at which a hydraulic system will or will not perform satisfactorily, it is recommended that sufficient testing be conducted and reviewed by both the user and manufacturer to ensure that required performance levels are met.

This recommended practice applies to self-propelled work machines as referenced in J1116.

This recommended practice has been proposed to recommend diagnostic port sizes and general guidelines for their use on construction and mobile equipment.

SAE J1298 covers the recommended diagnostic port sizes for use in measuring hydraulic fluid temperature, pressure, flow, and for obtaining fluid samples. See SAE J1502 for the detailed coupling specifications.

This SAE Standard specifies uniform methods for the testing and performance evaluation of threaded metallic tube connections and stud ends of ports for hydraulic fluid power.

This SAE Standard specifies uniform methods for the testing and performance evaluation of threaded metallic tube connections and stud ends of ports for hydraulic fluid power. Tests outlined within this document are independent of each other and document the method to follow for each test; see the appropriate component SAE or ISO standard for the test(s) requirements and the performance criteria. Appendix A of SAE J1644 is normative; Appendix B is informative.

This SAE Information Report is intended to provide design guidance in the selection of steel tubing and related tube fittings for general hydraulic system applications. The information presented herein is based on tubing products which conform to SAE J524, SAE J525, and SAE J356, and is subject to due consideration being given to the following limitations:

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 torque 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.
