J512J_197512
This standard covers complete general and dimensional specifications for the various types of tube fittings intended for general application in the automotive, appliance, and allied fields. Flare type fittings shall be as specified in Figs. 1-4 and Tables 1-3. NOTE: For sizes 3/16-3/8 and 1/2-3/4 the flare type fittings depicted in Figs. 1A-3C are identical with the corresponding refrigeration tube fittings specified in SAE J513. Special size combination fittings 3/16-3/8 and 1/2-3/4 shall be as specified in J513. Inverted flared type fittings shall be as specified in Figs. 5-11 and Tables 1, 4-7. Gages and gaging procedures pertaining to inverted flared tube fittings are given in Appendix A. NOTE: The seat dimensions specified in Table 4 are predicated on practical threading limitations in steel fittings and use of these fittings with double flared tubing.

J1394_198905
This standard covers the minimum requirements for metric sizes of nonmetallic tubing as manufactured for use in air brake systems. Nonreinforced products are designated type A and reinforced products type B. It is not intended to cover tubing for any portion of the system that operates below -40°C (-40°F), above +93°C (+200°F), above a maximum working gage pressure of 1.0 MPa (150 psi), or in an area subject to attack by battery acid. This tubing is intended for use in the brake system for connections that maintain a basically fixed relationship between components during vehicle operation. Coiled tube assemblies required for those installations where flexing occurs are covered by this standard and SAE J1131 to the extent of setting minimum requirements on the essentially straight tube and tube fitting connections, which are used in the construction of such assemblies.2
