Choice material in low bolt load applications
KLINGERSIL® C-6327 gasket material is a good choice for liquids and steams with low-temperature and low-pressure applications. Use in low bolt load applications. Controlled swelling in oils and fuels provides very good adaptability to any sealing surface. C-6327 offers excellent conformity to flanges at low surface bolts.
This material is manufactured with synthetic fiber reinforced with a modified SBR binder.
