Scope

This document specifies the general requirements and dimensions of flange heads, split flange clamps (FCS and FCSM), integral flange clamps (FC and FCM), oil ports, and installation surfaces for 42 MPa, four-screw fastened flange-clamp type hard pipe fittings and hose fittings (DN13~DN76); it also stipulates the requirements and dimensions of the sealing rings and sealing grooves used in conjunction with them.
This document applies to the connectors of hydraulic systems for industrial and commercial products where it is inconvenient to use threaded pipe fittings.
Note: This document recommends the use of metric threaded fasteners (Type 1, DN13~DN76), and also provides methods for using existing British threaded fasteners (Type 2, DN13~DN51).
