JUL2001 Issued1950-05 Revised2001-07 Superseding J514 JUN98 Hydraulic Tube Fittings 1.ScopeThis SAE Standard
4、covers complete general and dimensional specifications for 37 degree flared and flareless types of hydraulic tube fittings and O-ring plugs. Also included are pipe fittings and adapter unions for use in conjunction with these tube fittings. These fittings are intended for general application in hydr
5、aulic systems on industrial equipment and commercial products. These fittings are capable of providing leakproof, full flow connections in hydraulic systems operating at working pressures as specified in Table 1 for respective sections. Since many factors influence the pressure at which a hydraulic
6、system will or will not perform satisfactorily, the values shown in SAE J1065 should not be construed as a guaranteed minimum. For any application, it is recommended that sufficient testing be conducted and reviewed by both the user and fitting manufacturer to assure that performance levels will be
7、safe and satisfactory. SAE J514 Revised JUL2001 -2- The standard is divided into six sections as follows: Section 137 Degree Flare Tube Fittings Section 2Flareless Tube Fittings Section 3O-ring Plugs (for O-ring Ports see SAE J1926) Section 4Hydraulic Pipe Fittings (formerly SAE J926) Section 5Adapt
