J1926/3_201003: Connections 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 Ends

Features

Issuing Committee: Hydraulic Tube Fittings Committee

Scope

Content: This part of SAE 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 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 shall 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 the specification contained in this document to ensure that components made to this document comply with the performance rating.

Appendices A of this document is informative.

NOTE: This document specifies inch as well as metric hexes for the stud ends. Therefore, any product drawing specifying 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.

Rationale

Content

General revision for harmonizationwith SAE J514 and ISO 11926-3 and addition of sizes -40, -48 and -64 and converting the document to metric hex standard in accordance with FCCTC resolution on metric hex conversion. The resolution provides rationale for converting to metric hex and not using inch hex for new designs as follows:

“In an effort to standardize 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:
1. -
  lead to one global standard
2. -
  guide users to a preferred system
3. -
  reduce complexity
4. -
  eliminate duplication
5. -
  reduce confusion”
