Scope
This SAE Standard is intended to establish uniform performance criteria and methods of testing compression tube fittings with SAE J844 air brake tubing as used in vehicular air brake systems.
This document also establishes minimum qualifications for tensile and pressure capabilities, vibration durability under cyclic temperatures, serviceability, and fitting compatibility requirements. The specific tests and performance criteria applicable to the tubing are set forth in SAE J844.
NOTE: The test values contained in this performance standard are for test purposes only. For environmental and usage limitations, refer to SAE J844. For fittings, a type of fitting for use with SAE J844 nonmetallic tubing is included in SAE J246; however, it is not intended to restrict or preclude the use of other designs of fittings that comply with this document.
Rationale
The modifications to this document are to harmonize the requirements of SAE J1131 and SAE J2494-3 where applicable.

* 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.
