The Hose Set FLEX 4 is the connection hose with integrated ball valve. It is 1.5 m long, has a nominal diameter DN 8 and ends on the line side with a union nut with internal thread 3/8"; towards the filter head there is a FLEX connector piece as a 90° elbow, which is plugged into the FLEX receptacle and can be aligned in 30° increments. The ball valve allows the filter to be shut off without closing the main line or angle valve, which is helpful during cartridge changes and maintenance work. This variant is mostly used on the supply side; on the drain side, usually a set without shut-off is sufficient.
