Stem to Tube Reducers Series S6800 Allow fast connection and disconnection of plastic tube; it can be repeated several times and can be performed using one hand and without tools. The sealing ring (O-Ring) can be easily replaced if it is damaged or worn. This advantage derives from the simple execution of the internal collet, which can be extracted allowing the replacement of the O-Ring.
