I brought an ispring ro water filter only to find their saddle onlly fits a 1.5 pipe. My pipe was 2 inches. I ended up wasting a lot of time searching around for solutions to use their pipe. When I called them, the recommended this product but pointed me to local hardware stores or homedepot/lowes, but none of them had it. This thing was easy to use, drill hole, wrap around the pipe, then tighten.
