Gaskets used with graphite disks are stocked in the following materials: Neoprene, compressed fiber, solid PTFE, and PTFE envelope. Gaskets can be supplied loose or attached to the disk (Note: field replacement of gaskets NOT recommended on TWO-WAY Disks or Insulated Units)
When supplying your own gaskets, follow dimensions in the chart, especially the inside diameter which provides proper clearance to ensure accurate burst. 1/89 thick gasket is recommended. Gaskets for INSULATED Disks are made from high-temperature material and are always supplied attached.
