DN20-coupling set corrugated pipe
The DN20 corrugated pipe fitting kit includes a nut (brass nut M30 × 2), a clamping ring and a gasket.
Note! A connector tool is required for installation to blunt the pipe ends. Another option is, for example, the following. Place the nut on the pipe, carefully squeeze the clamping ring behind the second-to-last pipe wave, place a wide-head washer between the pipe end and the double nipple. After this, the nut is tightened tightly on the double nipple. You must be careful and careful when tightening so that the clamping ring does not break (do not overtighten the nut). After tightening, the pipe end should be blunt. The purpose is to make the pipe end wider and smoother for the gasket, and to make the connection tight.
