These fittings are capable of providing leakproof, full flow connections in hydraulic systems operating at working pressures as specified in SAE J1065, "Pressure Ratings for Hydraulic Tubing and Fittings."
Since many factors influence the pressure at which a hydraulic 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 safe and satisfactory.
The standard is divided into six sections as follows:
Section 1-37 Degree Flare Tube Fittings
Section 2-Flareless Tube Fittings
Section 3-O-ring Plugs (for O-ring Ports see SAE J1926)
Section 4-Hydraulic Pipe Fittings (formerly SAE J926)
Section 5-Adapter Unions (formerly in SAE J516)
Section 6-Tables for Calculating Dimensions on Special Sizes
