Abstract
A pneumatic plug is used to seal off a pneumatic pressure source from a pneumatic pressure seed meter. The pneumatic plug comprises an annular rim defining an annular cavity, a insert portion and a sealing wall. The plug is an integral rubber body. The insert portion is inserted into a pneumatic hose supplying pneumatic pressure to the seed meter. The annular rim defines an annular cavity into which the pneumatic inlet of the seed meter is received. The annular cavity is provided with two inwardly extending sealing ridges that engage the outer sidewalls of the pneumatic inlet. The sealing wall provides a pneumatic seal for the pneumatic hose.
