This SAE Recommended Practice is intended to provide design, interchangeable dimensions, testing procedures, performance requirements, and minimum identification for gladhand-type air line couplers used to connect the brake systems of trucks, truck-tractors, trailers, and dollies when these vehicles are joined to operate as a combination unit.
Rationale
This technical report has been revised to include the option of performing corrosion testing using the alternate approach detailed in the comprehensive SAE J2721 Recommended Practice. Other minor corrections and clarifications have been made as identified.
The Truck and Bus Supply and Control Components Committee of the Truck and Bus Brake and Advanced Driver Assistance Systems Steering Committee is responsible for developing, reviewing, and approving recommended practices, standards, and information reports related to air braked vehicles supply and components and their interfacing as utilized on trucks, tractor-trailers combinations and buses over 4,536 kilograms (10,000 lbs.) GVWR. The activities of this Committee include brake supply and control components and their interfacing, and is not, in any way, to duplicate efforts of any other Committees.
* 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.
