Q'ty :

SAE J844 is an engineering specification used in the North American automotive industry for air brake tubing systems.
It defines dimensional tolerances, material construction, and performance consistency requirements for non-metallic air brake tubing.

SAE J844 itself is not a regulatory standard.
When air brake tubing is used in road vehicles subject to U.S. transportation regulations,
the applicable assemblies must comply with DOT FMVSS 571.106 (FMVSS 106) requirements.
