Purpose

The three parts of SAE J1453 cover material, dimensional, and performance requirements of steel O-ring face seal (ORFS) connectors for tubing and the O-ring face seal interface and nut portion of hose stem assemblies for nominal tube diameters of 6 mm through 50 mm. SAE J1453-3 covers the requirements for O-ring face seal connectors to inch stud ends along with the associated adapters, bulkhead and union connectors. Inch hex dimensions of parts will be moved from the main document to an informative annex after 2013.

Field of Application

These connectors are intended for general application (see Figures 3, 4, and 5) and hydraulic systems on industrial equipment and commercial products, where elastomeric seals are acceptable to overcome leakage and variations in assembly procedures. These connectors are capable of providing leak proof full flow connections in hydraulic systems operating from 95 kPa vacuum to working pressures shown in Table 4. Since many factors influence the pressure at which a hydraulic system will or will not perform satisfactorily, these values should not be construed as guaranteed minimums. For any application, it is recommended that sufficient testing be conducted and reviewed by both the user and manufacturer to ensure that required performance levels are met.

For use of these connectors in conditions outside the pressure and temperature limits specified, the manufacturers must be consulted.

Both metric and inch tubing can be accommodated by changing only the sleeve to match the tube diameters. In the past, these connectors have been used predominantly with inch tubing. For new designs metric tubing should be considered.

The rated working pressure of a fluid conductor assembly using SAE J1453 hose stem connections or formed tube or braze-on tube connections shall not exceed rated working pressure of the lowest rated component thereof.
