Also included are recommended port dimensions and port design considerations. The flanged heads specified are incorporated into fittings having suitable means for attachment to tubes, pipes, or hoses to provide connection ends. These connections are intended for application in hydraulic systems, on industrial and commercial products, where it is desired to avoid the use of threaded connections. Flanged heads shall be as specified in Figure 3 and Table 1.

For Code 62 series, the maximum working pressure are Bar. However, the pressure rating of SAE flanges and connected equipment combination might vary from each other. For example: if a pipe connected to the flange has a lower maximum working pressure, it will result in an overall lower working pressure of the system. Therefore in a system, the item with the lowest pressure will be the maximum working pressure of the system.
Flanges with oring are has an advantage of prevent leakage as all metal-to-metal flanges are more prone to leakage. The configurations of SAE flanges are flat side, oring side or complete set. A complete set of SAE flanges are combination of flat side and oring side where it forms a seal between the flat surface and oring held in a recessed circular groove in the other half.
By tightening the bolts, it draws flat side and oring side together and compresses the oring. Because of the high pressure, it is important to note that every hydraulic or pneumatic system requires some form of fitting installation for completion.
