This SAE Standard covers complete general and dimensional specifications for refrigeration tube fittings of the flare type specified in Figures 1 to 42 and Tables 1 to 15. These fittings are intended for general use with flared annealed copper tubing in refrigeration applications. Dimensions of single and double 45 degree flares on tubing to be used in conjunction with these fittings are given in Figure 2 and Table 1 of SAE J533. The following general specifications supplement the dimensional data contained in Tables 1 to 15 with respect to all unspecified details.

This part defines performance requirements, dimensions, and designs for -2 through -32 internal and external hex port plugs for use in SAE J1926-1 ports. Testing and usage through many years confirm the performance requirements of port plugs made from carbon steel. The port plugs were specified in SAE J514 without any performance requirements. They have been developed and tested to gain a 4:1 working pressure rating for industrial applications. In fluid power systems, power is transmitted and controlled through a fluid (liquid or gas) under pressure within an enclosed circuit. In general applications, a fluid may be conveyed under pressure. Components are connected through their threaded ports by stud ends on fluid conductor fittings to tubes and pipes or to hose fittings and hoses. For threaded ports and stud ends specified in new designs in hydraulic fluid power applications, only ISO 6149 shall be used.

This SAE Standard covers specifications and performance requirements for 37 degree and 45 degree single and double flares for tube ends intended for use with SAE J512, SAE J513, SAE J514, and ISO 8434-2 connectors. The flares described in this document are intended for use with SAE metallic tube materials. Considerations such as the effects of wall thickness selection for specific working pressures, identifying appropriate length of thread engagements for specific applications with mating connectors and other associated criteria, shall be the responsibility of the user. For applicable nominal reference working pressures for hydraulic tubing, refer to SAE J1065 and ISO 10763. In an effort to standardize within a global marketplace and ensure that companies can remain competitive in an international market, it is the intent of this document to promote the use of metric tube and connector sizes, which will: Lead to one global system. Guide users to a preferred system. Reduce complexity.
