Consult the factory regarding your specific applications. See “Monomers”in Gasketing catalog Terms section.2. IFG® Style 5507 is rated “B”.3. There have been conflicting field reports concerning the suitability of NBRand neoprene bound gaskets in 123. End users should take note.4. IFG® Style 5507 is rated “A”.5. Some chromium plating baths contain fluorides that can attack silica andsilicate type fillers in some GYLON® styles. If the bath is known to containlittle or no fluoride, all GYLON® styles should be suitable for use.6. These GYLON® styles can be expected to be suitable to 60%concentration at temperatures up to 250°F (121°C).7. Use GYLON® styles 3502, 3503, 3505, 3562, 3563. These styles arespecially processed, cleaned and packaged for oxygen service.8. This GYLON® contains a stainless steel insert. There is a possibility thatthis might contribute traces of iron to form iron tannates, resulting inundesirable color in the tannic acid.9. These styles are not preferred choices for steam service, but aresuccessful when adequately compressed.10. If a gasketing material that conforms to FDA requirements is desired,contact factory for specific recommendations.11. These GYLON® gasket styles can be expected to be suitable to 75%concentration at temperatures up to 400°F (204°C).12. Minimum recommended assembly stress = 4,800psi.Preferred assembly stress = 6,000-10,000psi.Gasket thickness of 1/16” strongly preferred.For saturated steam above 150psig, consult Garlock Engineering.13. Some detergent solutions are strongly alkaline and/or may containbleach. Please contact Applications Engineering.14. Gylon 3545 is suitable for up to 200°F wet or dry fluorine gas. Abovethis please consult Applications Engineering.15. If lead chromate is also present please consult ApplicationsEngineering.15. If lead chromate is present, please contact Applications Engineering.
