Metallic Connections for Fluid Power and General Use - Part 3: NPTF Pipe Adapters and NPSM Adapter Unions
J514/3_202206
This part of SAE J514 covers general and dimensional specifications for NPTF pipe adapters and 30 degree NPSM adapter unions. These fittings are intended for general application in hydraulic systems on industrial equipment and commercial products.
These fittings are capable of providing leak-proof, full-flow connections in hydraulic systems operating at working pressures as specified in Table 6. Since many factors influence the pressure at which a hydraulic system will or will not perform satisfactorily, the values shown in Table 6 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.
Rationale:
SAE J514 was formerly organized as indicated in the foreword below. Part 3 of SAE J514 includes only pipe fittings, including rigid NPTF adapters and NPSM adapter unions.
In an effort to standardize within a global market and ensure that companies can remain competitive in an international market, it is the intent to convert to metric hex sizes, which will:
Lead to one global system.
Guide users to preferred system.
Reduce complexity.
Eliminate duplications.
Performance requriements have been revised to remove ambiguity.
Minimum stock sizes for female pipe listed in Table 12 have been revised due to a contradiction between the listed minimums and the stock sizes specified for adapter unions.
All dimensions are given in SI units. Except for nominal sizes and thread designations, U.S. customary units have been eliminated from this standard.
