Sioux Chief SmartSaddle tees allow to connect a 1-1/2” (Sch. 40/80) or 2” (Sch. 40) PVC pipe to an existing 3” or 4” PVC pipe without complex cutting and pipework. Simply cut a hole in the main pipe, prime & glue the surfaces and tighten the bands to secure the saddle tee in place. Smart Saddle offers a better and more reliable alternative to U-bolts and V-bolts which create pressure points on the pipe and could potentially cause cracks and leaks.
