Sierra part # 18-0476 riser block gaskets

The gaskets are constructed of a proven hi-temperature composite that does not contain asbestos materials. This gasket material has been designed to handle the high temperatures capable of exceeding 500 degrees Fahrenheit as well as harsh marine environments.

Each Sierra riser block-off gasket ensures the factory matched footprint of exhaust ports. The Typical thickness for these products can range up to 1/16". Be certain to thoroughly clean and remove the entire old gasket. When joining two non-machined surfaces, an exact match is not always possible. It is recommended that you use a thin layer of high-temperature silicone sealer on both sides of gasket prior to installation to create a more perfect reliable seal.
