Dynabrade 18578 Sander Polisher Valve Body Gasket

The Dynabrade 18578 Sander Polisher Valve Body Gasket forms a sealing interface between mating surfaces inside a sander polisher valve assembly, and blocking compressed air from escaping during operations and separating internal pressure zones within the valve body to control airflow direction across channels. It conforms to the housing contours to maintain alignment between the internal passages and supports consistent air routing through the tool, while reducing passage disruption across shifting components during activation of the valve mechanism. It is installed within the valve body section of the sander polisher between the housing and control components.
