ABSTRACT:
A condenser plug for a leaky condenser tube has a cylindrical external fluorocarbon tube body with an integral plug base and a flanged lip, a threaded bolt coaxially fixedly integrally secured wholly within the cylindrical external body and the plug base, and a non-rotatable bolt head permanently anchored in the plug base. A cooperative metal expander bolt has a tapered external cylindrical contour and a coaxial internal threaded sleeve with a flat metal cap. On threading the metal expander sleeve on to the fixed threaded bolt, the tapered expander bolt seats in the annular cylinder volume between the threaded bolt and the fluorocarbon plug body, expanding and extruding the plug body to firmly secure the plug body in the condenser tube. The tube leak is sealed between two condenser plugs disposed at the two opposed condenser tube ends secured in the pair of condenser sheets.
