This SAE Standard provides general and dimensional specifications for the most common hose fittings used in conjunction with hydraulic hoses specified in SAE J517 and utilized in hydraulic systems on mobile and stationary equipment.
The general specifications contained in Sections 1 through 17 are applicable to all hydraulic hose fittings and supplement the detailed specifications for the 100R-series fittings contained in the later sections of this document.
This document shall be utilized as a procurement document only to the extent agreed upon by the manufacturer and user.
Refer to SAE J517 for specifications of hose and information on hose assemblies. SAE J1273 contains information on application factors affecting hose fittings, hose, and hose assemblies.
The rated working pressure of a hose assembly comprising SAE J516 fittings and SAE J517 hoses shall not exceed the lower of the two working pressure rated values.
The following are hose fitting types contained in this document:
Male and female 45-degree flare hose fittings shall be as shown by the 37-degree flare figures and tables.
It is recommended that where step sizes or additional types of fittings are required, they be designed to conform with the specifications of this document insofar as they may apply. The following general specifications shall supplement the dimensional data contained in the tables with respect to all unspecified detail.
This revision of SAE J516 corrected some typographical errors, included additional verbiage for larger size hexes used on swivel nut fittings, and added Section 17.

Hydraulic Hose and Hose Fittings Committee
The Hydraulic Hose and Hose Fittings Subcommittee of the FCCTC develops and maintains SAE Standards, Recommended Practices and Information Reports relating to hydraulic hose and hose fittings with an intended use in pressure applications. Participants in the FCCTC Hydraulic Hose and Hose Fittings Subcommittee include OEMs, suppliers, consulting firms, government and other interested parties.
* Redlines comparisons are available for those standards listed in the Revision History that contain a radio button. A redline comparison of the current version against a revision is accomplished by selecting the radio button next to the standard and then selecting 'compare'. At this time, Redline versions only exist for some AMS standards. SAE will continue to add redline versioning with ongoing updates to SAE MOBILUS.
