Product Information
It is a genuine gasket that is supplied directly from the original manufacturer for use with Honda engines commonly installed on lawn and garden equipment. This replacement gasket is used to create an air-tight seal for the muffler assembly, for correct location and uses make sure to check appropriate diagrams of your equipment. Over time the material may get compressed and crack eventually requiring replacement to maintain the proper seal. Please note this high quality composite material gasket is sold individually.
