This standard covers complete general and dimensional specifications for 37 deg flared and flareless types of hydraulic tube fittings and the O-ring bosses and related components with which they assemble. These fittings are intended for general application in hydraulic systems on industrial equipment and commercial products. The 37 deg flared tube fittings shall be as shown in Figs. 5-18 and Tables 3-6. Since the basic design of these fittings is derived from Air Force and Navy Standards for 37 deg flared fittings which meet a performance specification, any future changes should not be detrimental to the design or performance. Dimensions for double and single 37 deg flares on tubing to be used with these fittings are given in Fig. 3 and Table 2 of SAE J533. The flareless tube fittings shall be as shown in Figs. 19-32 and Tables 7-10. The basic design of these fittings is derived from existing military standards.
