Universal threaded tapping saddle with blade shut-off for under pressure tapping on metal pipes. For drinking water and neutral liquids to max. 70° C
AVK tapping saddles are easy to mount, maintenance free and designed for long life. The stirrup is rubber lined for optimal protection of the pipe. A conical POM washer enables easy angling of the bolts thus giving the stirrup optimum flexibility. A large profiled rubber gasket of EPDM ensures a drop tight seal against a rough pipe surface. When using a shut-off blade it is not necessary to use a service connection valve when drilling into a mainline.
