Abstract
A plug for a threaded port is formed of resilient elastomeric material and has upper and lower ends. A smooth non-threaded outer cylindrical wall is disposed between the ends. The outer cylindrical wall has an outer diameter sufficient to frictionally engage the threads of the port. An outwardly protruding collar is disposed between the upper end and the outer cylindrical wall. An annular bead is integrally formed on the collar and is adapted to sealingly engage an inner peripheral surface of the port.
