fillers, mostly in utility lines, may get some info AWWA
The PTFE Filler Flanges are used to connect flanges with raised faces
or sealing surfaces-especially those of plastic lined steel pipe-to
flat faced plastic flanges. Without filler flanges, when the bolts are
tightened on such a joint, the plastic flange will, most likely,
break. The filler flange fills the gap that lies between the OD of the
raised surface and the OD of the flange, flattening the face in
contact with the plastic flange.
Reducing Flange Fillers can be furnished for connecting pipe of two
different diameters. In such cases, the fillers have two sets of bolt
holes with one or both sets of holes tapped for studs.
