DEFINITION

Classification: 439/190

HAVING RETAINER OR PASSAGEWAY FOR FLUENT MATERIAL:

(under the class definition) Electrical connector with a provision to (a) confine a flowable medium or (b) confine the flow of such a medium.

(1) Note. A hydraulic drive is not considered to meet the limitations of this subclass.
