Wedge rings


The G-ST wedge ring is a component consisting of two shells and a rubber gasket (also with drinking water certification) in order to make adjustments during assembly and thus easily compensate for misalignments or excessive flange leaf distances. The G-ST wedge ring can be continuously adjusted from 0 ° to 8 °, allowing the course of the pipeline to be adapted without additional time-consuming welding work.

The ideal combination consists of a G-ST wedge ring and two G-ST-gasket.
