PTFE Ring Gaskets, unaffected by corrosive chemicals or solvents, are used whenever resistance to chemical attack or non-contamination of a product is required. Available from stock in pipe sizes from ½” through 24” as standard, ring gaskets are made by die-cutting the desired shape from a molded or skived sheet, by machining from a molded tube or by molding from PTFE powder. These gaskets can be fabricated to custom specifications in all sizes. Ring gaskets are available in PTFE and any PTFE.
