Description: Push Nipple with Gasket is used by attaching to a 22 x 22 square PVC pipe with a gasket. Because the nipple top is separable and because of the structure of the pipe connection gasket, it is not suitable to be used with a Ø 26,7 mm round PVC pipe. Usage with a round pipe is only possible after custom production. Please contact us for such requests. Nipple gasket is manufactured from nitrile rubber. Standard production water passage values: 70 ml/ minute ( at 20 mbar)
