DEFINITION

Classification: 137/231

(under subclass 223) Apparatus having significant structure for connecting a filling chuck to an inflation stem, or an inflation stem to a second inflation stem or filling tube, the second stem or tube usually being permanently associated

with a tire.

(1) Note. The mere statement that a chuck or stem is screw threaded or flanged for coupling is not regarded as significant coupling structure for this subclass.
