5、J1926-3 MAR2010Connections for General Use and Fluid Power - Ports and Stud Ends with ASME B1.1 Threads and O-Ring Sealing - Part 3: Light-Duty (L-Series) Stud EndsRATIONALEThis document was revised in order to move the optional inch hex sizes and dimensions to Appendix B.In an effort to standardize

6、 within a global market and ensuring that companies can remain competitive in an international market, it is the intent to convert to metric hex sizes which will: lead to one global system guide users to preferred system reduce complexity eliminate duplicationsThe optional inch hexes now contain the

7、 note “NOT TO BE USED FOR NEW DESIGN” in accordance with the Metric Hex Resolution approved during the March 2008 FCCTC meeting. FOREWORDSAE J1926 consists of the following parts, under the general title:Connections for general use and fluid power Ports and stud ends with ASME B1.1 threads and O-rin

8、g sealing: Part 1: Port with O-ring Seal in Truncated Housing Part 2: Heavy-Duty (S Series) Stud Ends Part 3: Light-Duty (L Series) Stud EndsThese standards define performance requirements, dimensions, and designs for port and stud end connections for heavy-duty in Part 2 and light-duty in Part 3. S

9、ignificant testing through 50 years of use has confirmed the performance requirements of these ports and stud ends. SAE J1926-3 stud ends originated with 37 flare connectors shown in SAE J514.In fluid power systems, power is transmitted and controlled through a fluid (liquid or gas) under pressure w

10、ithin an enclosedcircuit. In general applications, a fluid may be conveyed under pressure. Components are connected through their threaded ports by stud ends on fluid conductor fittings to tubes/pipes, or to hose fittings and hoses.SAE INTERNATIONAL J1926-3 SEP2016 Page 2 of 141. SCOPEThis part of S

11、AE J1926 specifies dimensions, performance requirements, and test procedures for adjustable and nonadjustable light-duty (L series) stud ends with ASME B1.1 threads for use in fluid power and general applications and the O-rings used with them.Stud ends in accordance with this part of SAE J1926 may

12、be used at working pressures up to 35 MPa for nonadjustable and adjustable stud ends. The permissible working pressure depends upon materials, design, working conditions, application, etc.For threaded ports and stud end specified in new designs for hydraulic fluid power applications, only ISO 6149 s

13、hall be used. Threaded ports and stud ends in accordance with ISO 1179, ISO 9974, and ISO 11926 shall not be used for new design in hydraulic fluid power applications.Conformance to the dimensional information does not guarantee rated performance. Each manufacturer shall perform testing according to

14、 the specification contained in this document to ensure that components made to this document comply with the performance rating.Appendices A and B of this document are informative.NOTE: This document specifies inch as well as metric hexes for the stud ends. Therefore, any product drawing specifying

15、 stud ends in accordance with this document must specify hex type, inch or metric, to assure getting intended hex.Stud ends or parts specified before January 1, 2010 using this standard, shall be supplied with inch hexes, unless otherwise specified.2.

34、EFINITIONSFor the purpose of this part of SAE J1926, the definitions given in ISO 5598 and the following shall apply.3.1 ADJUSTABLE STUD ENDA stud end connector that allows for fitting orientation before final tightening of the locknut to complete the connection. This type of stud end is typically u

35、sed on shaped fittings (e.g., tees, crosses, and elbows).3.2 NONADJUSTABLE STUD ENDA stud end connector that does not require specific orientation before final tightening of the connection because it is typically used on straight fittings.4. STUD END4.1 Size DesignationThe stud ends shall be designa

36、ted by SAE J1926-3 and the thread size, separated by a colon, for example, SAE J1926-3: 1/2-20. Products drawings specifying this stud end shall have the type of hex, inch or metric, listed.4.2 Reduced Size Stud Ends for Jump Size ConnectorsFor jump size connectors where the hex size of the other en

37、d, e.g. tube/hose end, is larger than the stud hex “V” in Tables 1and 6, a shoulder may have to be turned to the appropriate diameter and length to avoid interference with the port spot face.
