Ceramic Paper Ring Gasket
4" 150# Ring Gasket 1/8" Ceramic PaperProduct Code: SGI-550-0442
Ceramic Paper Ring Gaskets are made from LyTherm® Rollboard paper, which is a lightweight refractory material processed from a blend of high purity alumina-silica fibers into a highly flexible, uniform insulation media. It is recommended for continuous use at temperatures up to 2300°F (1260°C).
LyTherm® Rollboard is a utility grade paper that has low shrinkage, good handling strength, and low thermal conductivity. It contains a small amount of organic binder for processing, which makes it flexible, yet reduces off gassing and odor during use. It’s flexibility allows it to be wrapped or rolled to fit most complex configurations.
This gasket is available in Ring and Full Face shape.
