Made from a hard-wearing rubber compound suitable for compressed-air tools, it is a straightforward service item that can be replaced during routine maintenance to reduce downtime and extend tool life. It is intended for use in Sullair SK12 breakers and other assemblies that specifically call for this MPN.
