NOTES:
1. Consult the factory regarding your specifc applications. See
"Monomers" in Gasketing Terms Section, page C-52.
2. IFG
®
Style 5507 is rated “B”.
3. There have been conficting feld 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 fuorides that can attack silica
and silicate type fllers in some GYLON
®
styles. If the bath is known to
contain little or no fuoride, all GYLON
®
styles should be suitable for
use.
6. These GYLON
®
styles can be expected to be suitable to 45-59% con-
centration 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 specifc recommendations.
11. These GYLON
®
gasket styles can be expected to be suitable to 75%
concentration at temperatures up to 400°F (204°C).
12. Not a fre-tested material.
13. Minimum recommended assembly stress = 4,800 psi.
Preferred assembly stress = 6,000-10,000 psi.
Gasket thickness of 1/16" strongly preferred.
For saturated steam above 150 psig, consult Garlock Engineering.
14. Styles 2900 and 2950 exhibit identical chemical resistance proper-
ties.
