Soft Filler Material: Flexible materials like graphite, PTFE, or mica fill the spaces between the metal windings to improve sealing performance. Outer & Inner Rings (Optional): Outer Guide Ring: Ensures proper gasket centering on the flange. Inner Ring: Enhances stability and prevents excessive compression.
