ABSTRACT:
A leak test port plug device is disclosed which includes a resilient plug having a first portion which is substantially cylindrical and a second portion which is generally conical and formed in integral one-piece relationship to the first portion. When the first portion is inserted into a port of a component to be tested and the plug is compressed, the first portion radially expands in the port and the second conical portion moves into the end of the port to effectively seal the port against fluid leakage.
