Abstract

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. Specifications for straight thread O-ring bosses into which connector and adjustable styles of hydraulic tube fittings assemble are given in Fig. 34 and Table 12 . O-ring boss plugs shall be as shown in Fig. 35 and Table 13 . Modification of hexagon chamfers on standard fittings when used in MS 33649 (or superseded AND 10050) type O-ring bosses is covered in Fig. 33 and Table 11 . For specifications of O-rings used in conjunction with these fittings, see SAE J515. For guidance in the selection of steel tubing for any pressure using these fittings see SAE J1065—Pressure ratings for Hydraulic tubing and fittings. Also included are Tables 14 to 24 and Figure 38 and instructions which may be used for determining the overall lengths, leg lengths, and stock sizes applicable to special size combination fittings not covered in the standard dimensional tabulations. The following general specifications supplement the dimensional data contained in Tables 3 - 13 with respect to all unspecified detail.
