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

This standard applies to self-propelled work machines as referenced in SAE J1116 JUN86.

This SAE Standard includes complete general and dimensional specifications for those types of filler and drain plugs (shown in Figures 1 to 7 and Tables 1 to 3) having straight threads which are commonly used with gaskets or seals in automotive and related industrial applications.

This part of SAE J2244 specifies dimensions, performance requirements, and test procedures for metric adjustable and nonadjustable light-duty (L series) stud ends and O-rings. Stud ends in accordance with this part of SAE J2244 may be used at working pressures up to 40 MPa for nonadjustable stud ends and 31.5 MPa for adjustable stud ends. The permissible working pressure depends upon materials, design, working conditions, applications, etc. For threaded ports and stud ends for use in new designs in hydraulic fluid power applications, only SAE J2244 shall be used. Threaded ports and stud ends in accordance with ISO 1179, ISO 9974, and SAE J1926 (ISO 11926) shall not be used in new designs in hydraulic fluid power applications. Conformance to the dimensional information in this SAE Standard does not guarantee rated performance.

This part of SAE J2244 specifies dimensions, performance requirements, and test procedures for metric adjustable and nonadjustable heavy-duty (S Series) stud ends and O-rings. Stud ends in accordance with this part of SAE J2244 may be used at working pressures up to 63 MPa for nonadjustable stud ends and 40 MPa for adjustable stud ends. The permissible working pressure depends upon materials, design, working conditions, application, etc. For threaded ports and stud ends for use in new designs in hydraulic fluid power applications, only SAE J2244 shall be used. Threaded ports and stud ends in accordance with ISO 1179, ISO 9974, and SAE J1926 (ISO 11926) shall not be used for new designs in hydraulic fluid power applications. Conformance to the dimensional information in this standard does not guarantee rated performance.

This part of SAE J2244 specifices dimensions, performance requirements, and test procedures for metric external hex O-rings port plugs. Port plugs in accordance with this part of SAE J2244 may be used at working pressures up to 63 MPa. The permissible working pressure depends upon materials, design, working conditions, applications, etc. For threaded ports and stud ends for use in new designs in hydraulic fluid power applications, only SAE J2244 shall be used. Threaded ports and stud ends in accordance with ISO 1179, ISO 9974, and SAE J1926 (ISO 11926) shall not be used in new designs in hydrualic fluid power applications. Conformance to the dimensional information in this document does not guarantee rated performance. Each manufacturer shall perform testing according to the specification contained in this document to ensure that components made to this document comply with the performance ratings.

This SAE Standard covers normalized electric resistance welded flash controlled single-wall, low-carbon steel pressure tubing intended for use as pressure lines and in other applications requiring tubing of a quality suitable for bending, flaring, beading, and brazing.

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 SAE 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 SAE Information Report is primarily intended for mobile/stationary industrial equipment applications.

This SAE Standard covers material, dimensional, and performance requirements of steel O-ring face seal fittings for tubing and the O-ring face seal interface and nut portion of hose stem assemblies for nominal tube or hose diameters 6.35 mm (0.250 in) through 38.1 mm (1.500 in). These fittings are intended for general application and hydraulic systems on industrial equipment and commercial products, where elastomeric seals are acceptable to overcome leakage and variations in assembly procedures. These fittings are capable of providing leak-proof full flow connections in hydraulic systems operating from 95 kPa (28 in Hg) vacuum to working pressures shown in Table 1. Since many factors influence the pressure at which a hydraulic system will or will not perform satisfactorily, these values should not be construed as guaranteed minimums.
