This SAE 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.

 

Inverted flared type fittings shall be as specified in Figures 5 to 11 and Tables 3, 6, 7, 8, and 9. Gages and gaging procedures pertaining to inverted flared tube fittings are given in Appendix A.

NOTE: The seat dimensions specified in Table 6 are predicated on practical threading limitations in steel fittings and use of these fittings with double flared tubing. Therefore, wherever purchasers contemplate using these fittings with single flared tubing, it is recommended that the optional inverted flare nut (Figure 9A) be used.
