DEFINITION

Classification: 137/507

(under subclass 494) Apparatus combined with means for mounting the apparatus on or connecting it with the system from which the apparatus derives its fluid.

(1) Note. Merely naming a conventional coupling such as an internally threaded collar is insufficient for classification in this subclass. There must be a recitation of the relationship of the mounting or connecting means to the system which is the fluid source.
