Product Notes:
Filler Flanges, also known as Compensation Rings, 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.
BASE PART NUMBER: As shown here, the BASE PART NUMBER defines the Series (two characters), the material (one character), the nominal size, and the thickness TH. Use a decimal number to indicate the nominal size. For example, a 3/4” PTFE Filler Flange x 1/8” thick would be FFT-0.75-0.125
NOTE: Other materials available, contact factory.
