Sierra gaskets are constructed from proven, hi-temperature composites, capable of reaching over 500 degrees Fahrenheit. The gaskets do not include harmful asbestos materials, which give off harmful fumes when heated. They are capable of withstanding higher heat and pressures, which are commonly found in the marine environment.

In past years, gasket manufacturers have relied on asbestos to be the primary fiber material found in gaskets due to its ability to handle heat over long periods of time. Today, Sierra utilizes armid fibers, in addition to their composite blend of material, creating a gasket that meets or exceeds the demands of the seals recommend by the engine manufacturer.

Full StarFull StarFull StarFull StarEmpty StarPretty good
by Bruce from Woodinville, Washington on August 06, 2013
I had no issue with the quality of the gaskets. I wish there was a diagram or list of which gasket went where, included in the package. Most are obvious, but some are a little mysterious to me. Maybe if I disassembled further, I would see where the rest of the gaskets went??? Sealant or not, was a question too. The head gasket was labeled no sealant, but the others...........
