Equalseal EQ 505 is a true re-structured PTFE gasket sheet with excellent physical properties to be used in the most demanding applications. Its unique construction which includes premium PTFE resin and glass microspheres limits the cold flow problems associated with skived PTFE sheets. Equalseal EQ 505 is more compressible than other styles of restructured PTFE and is effective in applications where bolt load is limited by equipment design. Equalseal EQ 505 gaskets are unbranded and carefully cleaned, package, and certified for use in oxygen service.
