Specification of LATTY graf EFI GRAPHITE SHEET
DESCRIPTION
LATTYgraf EFI
EXPANDED GRAPHITE AND STAINLESS STEEL SHEET AND GASKET FOR STATIC SEAL APPLICATIONS
Gasket material made of high-purity expanded graphite material (>98%) bonded and laminated over a ISO 1.4401 stainless steel 50µ foil. The medium rigidity of LATTYgraf EFI permits on site easy gasket cutting and fast installation in inaccessible locations where gasket flexing is necessary. Limitation : Prefer LATTYgraf EFA for high Pressure/Temperature rating, and LATTYgraf EFN for chloride environment. Graphite gasket for high-temperature applications.
Fluids : All environments (except strong oxidising ones)
Material : Pipework flange gaskets, casing cover gaskets for valves, manhole gaskets.
