Description
Frederickseal Style 350N Single Jacketed Copper Gasket consists of a partially exposed soft, malleable inner core material, wrapped in a thin copper jacket.
The core material can be anything from standard non-asbestos to Unifoil (flexible graphite). It combines the flexibility and sealing properties of the inner material with the strength, resistance to high temperatures, and corrosion resistance of the copper jacket.
It is used primarily for small diameter openings with narrow flanges and is recommended for medium to high pressure and temperature ranges.
