Description / Abstract:
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.
Purpose
The purpose is to provide coupler halves for brake lines on one
vehicle that will be identified and compatible with the coupler
halves on the brake lines of another vehicle.
