ISO 6162-2:20 18给出了法兰头、分体式法兰夹（FCS和FCSM）、一体式法兰夹（FC和FCM）、端口和安装表面的一般和尺寸规范，适用于在42 MPa（420 bar[1]）压力下使用的四螺钉、分体式和一体式法兰夹类型的管接头和软管接头。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 6162-2:20 18还认识到需要适应公制螺钉紧固件（类型1）（适用于DN 13至DN 76），以及提供一种使用现有英制螺钉紧固件（类型2）（适用于DN 13至DN 51）的方法。 这些连接旨在应用于工业和商业产品上的液压系统中，其中期望避免使用螺纹连接器。 [1]1巴=0.1 MPa=105巴；1Pa=1N/m2。

ISO 6162-2:2018 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 a pressure of 42 MPa (420 bar[1]). It also specifies the dimensions of the seals to be used, as well as the grooves that house the seals. ISO 6162-2:2018 also recognizes the need to accommodate metric screw fasteners (type 1) (for DN 13 to DN 76), as well as to provide a means to use existing inch screw fasteners (type 2) (for DN 13 to DN 51). 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.
