Scope
This SAE Standard covers specifications and performance requirements for 37 degree and 45 degree single and double flares for tube ends intended for use with SAE J512, SAE J513, SAE J514, and ISO 8434-2 connectors. The flares described in this document are intended for use with SAE metallic tube materials. Considerations such as the effects of wall thickness selection for specific working pressures, identifying appropriate length of thread engagements for specific applications with mating connectors and other associated criteria, shall be the responsibility of the user. For applicable nominal reference working pressures for hydraulic tubing, refer to SAE J1065 and ISO 10763.
In an effort to standardize within a global marketplace and ensure that companies can remain competitive in an international market, it is the intent of this document to promote the use of metric tube and connector sizes, which will:
-
Lead to one global system.
-
Guide users to a preferred system.
-
Reduce complexity.
-
Eliminate inventory duplications.
Rationale
The 37 degree double flare wall thickness of 1.25 mm for the 10 mm OD tube in Table 2 and 1.24 mm for the 9.52 mm OD in Table 3 were changed to 1 mm and 0.89 mm, respectively. This was done to resolve issues for manufacturers and users where it was difficult to hold the form resulting in thread engagement loss and stripping of threads when assembled. This condition was especially pronounced using stainless steel tubing. A footnote related to this was added to the tables.

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.
