GF Signet PVC saddle type installation fitting is easily retrofit onto existing PVC piping systems. They can be installed in both SCH40 and SCH80 piping. Includes 4 pieces, 2 wedges, top shell, bottom shell and water-tight sealing gasket. Refer to the photo gallery for visual.

For a 2″ – 8″ diameter pipe size, they will require a 1  5/8″ hole saw to drill into the pipe. Configurations are also offered to install pre-assembled with plain end pipe connections.  Each saddle comes with a water tight gasket, as shown in the photos in the gallery that is to be sandwiched between the fitting and the piping, around the 1 5/8″ hole, when assembling the saddle.

Be sure to depressurize and vent piping systems prior to installation. GF signet installation fittings are NSF certified. See here for installation instructions.
