Hydraulic fluid power - Flange connectors with split or one-piece flange clamps and metric or inch screws - Part 1: Flange connectors for use at pressures of 3,5 MPa (35 bar) to 35 MPa (350 bar), DN 13 to DN 127

This part of ISO 6162 specifies complete general and dimensional characteristics for flange heads, split flange clamps (FCS), one-piece flange clamps (FC) and ports applicable to four-screw, split and one-piece flange clamp type tube and hose connectors for use at pressures of 3,5 MPa (35 bar1)) to 35 MPa (350 bar). It also specifies the dimensions of the seals to be used, as well as the grooves to house the seal.
This part of ISO 6162 also recognizes the need to accommodate metric (type 1) screw fasteners, as well as to provide a means to use existing inch (type 2) screw fasteners.
These connectors are intended for application in hydraulic systems on industrial and commercial products, where it is desired to avoid the use of threaded connectors.
Surges of pressure higher than the nominal ratings will reduce the ability of the flange connectors to retain the hydraulic fluid. This shall be taken into account in the design of the hydraulic system.
1) 1 bar = 0,1 MPa = 105 Pa: 1 Pa = 1 N/m2.
