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.

[ What is claimed is:] [1.] A plug to close and seal an outer end of a threaded orifice in a body member, comprising:a plug of resilient elastomeric material having generally opposite upper and lower ends and a smooth non-threaded outer cylindrical wall disposed therebetween, the outer cylindrical wall having an outer diameter sufficient to frictionally engage the threads of the threaded orifice, the lower end of the plug being closed;an outwardly and upwardly sloped collar integrally formed on the plug and disposed between the upper end and the outer cylindrical wall, the collar protruding outwardly from the outer cylindrical wall;a continuous annular bead integrally formed on the collar and being adapted to sealingly engage a sealing surface on the orifice, thereby defining a primary sealing surface of the plug.
