This document gives general and dimensional specifications for flanged heads, flange clamps, ports and
mounting surfaces applicable to four-screw, one-piece square flange clamp type tube connectors and
hose fittings for use at a pressure of 42 MPa [420 bar1)]. It also specifies the dimensions of the seals to
be used, as well as the grooves that house the seals.
These connections are intended for application in hydraulic systems on industrial and commercial
products where it is desired to avoid the use of threaded connectors.
