Description: Nipple Drinker with Screwed is used by directly screwing it to a 22x22 mm PVC pipe. Because the nipple top is separable it is not suitable to be used with a Ø 26,7 mm round PVC pipe. Installation using the threaded connector is also not recommended. Usage apart from direct screwing to a square pipe requires special forms. Please contact us for such requests. Standard production water passage values: 70 ml/ minute ( at 20 mbar)
