ISO 6162-1:2012给出了适用于在3.5 MPa（35巴）至35 MPa（350巴）压力下使用的四螺钉、分体式和分体式法兰卡箍式管接头和软管配件的法兰头、分体式法兰卡箍（FCS和FCSM）、一体式法兰卡箍（FC和FCM）、端口和安装面的一般和尺寸规范。它还规定了要使用的密封件的尺寸，以及容纳密封件的凹槽。 ISO 6162-1:2012还认识到需要容纳公制螺钉紧固件（1型），以及提供使用现有英制螺钉紧固件（2型）的方法。 这些接头适用于工业和商业产品上的液压系统，避免使用螺纹接头。 高于标称额定值的压力波动将降低法兰连接保持液压油的能力。 在设计液压系统时需要考虑到这一点。

ISO 6162-1:2012 gives general and dimensional specifications for flanged heads, split flange clamps (FCS and FCSM), one-piece flange clamps (FC and FCM), ports and mounting surfaces applicable to four-screw, split and one-piece flange clamp type tube connectors and hose fittings for use at pressures of 3,5 MPa (35 bar ) to 35 MPa (350 bar). It also specifies the dimensions of the seals to be used, as well as the grooves that house the seals. ISO 6162-1:2012 also recognizes the need to accommodate metric screw fasteners (type 1), as well as to provide a means to use existing inch screw fasteners (type 2). 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. Surges of pressure higher than the nominal ratings will reduce the ability of the flange connections to retain the hydraulic fluid. This needs to be taken into account in the design of the hydraulic system.
