This support ring is made of steel covered with a TFE machined envelope over a compressed fiber gasket. Clamp the support ring between two column sections. For 225 mm size and over, we recommend using a TFE Crescent Ring Gasket (Cat. Ref. TR) on each side of the plate. This makes it easier to get a tight seal, and you can reuse the support ring when you wish. 
The ring supports either the ceramic packing support plate or the ceramic distributor plate. This ring lets you remove an entire packed section without having to remove the packing first.
