Notes:

  1. Consult the factory regarding your specific applications.
  2. IFG® Styles 5500 and 5507 are rated "B".
  3. There have been conflicting field reports concerning the suitability of NBR and neoprene bound gaskets in 123. End users should take note.
  4. IFG® Styles 5500 and 5507 are rated "A".
  5. Some chromium plating baths contain fluorides that can attack silica and silicate type fillers in some GYLON® styles. If the bath is known to contain little or no fluoride, all GYLON® styles should be suitable for use.
  6. These GYLON® Styles can be expected to be suitable to 45-59% concentration at temperatures up to 250ºF (121ºC).
  7. Use GYLON® Styles 3502, 3503, 3505, 3562, 3563. These GYLON® styles are specially processed, cleaned and packaged for oxygen service.
  8. This GYLON® contains a stainless steel insert. There is a possibility that this might contribute traces of iron to form iron tannates, resulting in undesirable color in the tannic acid.
  9. Styles CP-3900, 3000 and 3001 are not preferred choices for steam service.
  10. If a gasketing material that conforms to FDA requirement is desired, contact factory for specific recommendations.


WARNING:
Properties/application shown here are typical. Your specific application should not be undertaken without independent study and evaluation for suitability. For specific application recommendations consult Garlock. Failure to select the proper sealing products could result in property damage and/or serious personal injury.

Performance data published here has been developed from field testing, customer field reports and/or in-house testing.
