Recommendations for use The temperature and pressure recommendations in the graphs apply to gaskets 2.0 mm / 0.08 inch thick that are used with raised face flanges. Higher stresses are possible when thinner gaskets are used. The recommendations are based on material characteristics and installation conditions. The information provided should therefore be considered cautious estimates rather than specific operational limits. Water/water vapor WWW.TRELLEBORG.COM/SEALS Copyright © 2022 Trelleborg AB (publ).
