This SAE standard covers complete general and dimensional specifications for the flanged heads and split flange clamp halves applicable to 4-bolt split flange type tube, pipe, and hose connections with appropriate references to the O-ring seals and attaching components used in their assembly. 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.
