What is the difference between a Companion Flange and a Blind Flange?

  • A Companion Flange is a flange that has a hub that is either socket or threaded that you would attach to your pipe.
  • A Blind Flange is solid in the middle and you would bolt to a companion flange to terminate a line. This type of flange does not have a hub.
  • We also offer a Van Stone Flange that allows for easy aligning because it has an independent flange that rotates around the hub.

Our PVC and CPVC pipe flanges come with bolt holes so that you can bolt two flanges together with a gasket in between to provide a leak proof connection.
