While it's true that paint sprayers come with different features across companies, some pump parts are perfectly compatible and can be used interchangeably. For instance, you can use a Titan hose in a Graco sprayer as long as the connectors have the same thread size as the one you're replacing. Another compatible feature is the spray tip. Titan and Graco share the same tip seats. Although some Graco tips have rubber washers instead of plastic, metal seats can be used interchangeably in either guard.
