Abstract

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. Refer to SAE J1131 for the performance requirements of reusable (push to connect) fittings intended for use in automotive air brake systems. NOTE: For sizes 3/16 to 3/8 and 1/2 to 3/4, the flare-type fittings are identical with the corresponding refrigeration tube fittings specified in SAE J513. Special size combination fittings 3/16 to 3/8 and 1/2 to 3/4 shall be as specified in SAE J513. Inverted flared-type fittings shall be as specified. Gauges and gauging procedures pertaining to inverted flared tube fittings are given in Appendix A. NOTE: The seat dimensions 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 be used. Tapered sleeve compression-type fittings intended for general use with annealed copper alloy tubings shall be as specified. To assure satisfactory performance, spherical sleeve compression-type fitting components (refer to SAE J246) should not be intermixed with tapered sleeve compression-type fitting components when assembling connections in areas where both types are available. Dimensions of single and double 45-degree flares on tubing to be used in conjunction with flared and inverted flared fittings are given in SAE J533.
