NOTES:
If fire resistant gaskets are required please consult Fire Tests under Gasket Terms, or contact Applications Engineering.
1. Consult the factory regarding your specific applications.
2. IFG® Style 5507 is 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® Style 5507 is 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 250°F (121°C).
7. Use GYLON® styles 3502, 3503, 3505, 3562, 3563. These 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. These styles are not preferred choices for steam service, but are successful when adequately compressed.
10. If a gasketing material that conforms to FDA requirements is desired, contact factory for specific recommendations.
11. These GYLON® styles can be expected to be suitable to 75% concentration at temperatures up to 400°F (204°C).
12. Not a fire-tested material.
13. For saturated steam above 150 psig, consult Garlock Engineering. Minimum recommended assembly stress = 4,800 psi. Preferred assembly stress = 6,000-10,000 psi.
14. Styles 2900 and 2950 exhibit identical chemical resistance properties.
15. Some detergent solutions are strongly alkaline and/or may contain bleach. Please contact Applications Engineering.
