SAE J518/2_202312

This SAE Standard covers general and dimensional specifications for the Code 62 metric (Type 1) and inch (Type 2) flanged heads, flange clamps (FC and FCM), and split flange clamps (FCS and FCSM) applicable to four-screw flange type tube, pipe, and hose connections. Also included are the recommended port dimensions and port design considerations. Type 2 (inch) flange clamps and split flange clamps are not for new design. The flanged heads specified are incorporated into fittings having suitable means for attachment of 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. The rated working pressure of an assembly shall not exceed the least of all the component working pressure rated values. The following general specifications supplement the dimensional data contained in the tables with respect to all unspecified detail. Parts manufactured to this standard are interchangeable with ISO 6162-2 and connectors to either standard can be supplied with the exception of the -40 and -48 Type 2 connections that are included in SAE J518-2, but not ISO 6162-2. This revision updates the last draft proposal of SAE J518-2 applicable and reference document names and numbers throughout the document; the “Corrosion Protection” section was updated to the committee’s current standard language; and one sentence in the tolerance section was deleted to avoid confusion. The content of one standard, ASME B18.22.2, was placed in multiple other standards and then the standard was withdrawn. These other standards are referenced, the old deleted, and necessary language changes are made. Also changed is correcting a reference to a column in Tables 1A and 1B from “Working Pressure” to the column name of “Maximum Working Pressure.”
