Abstract
A leak test adapter system and method for using same are provided for leak esting a container. A test port is defined in the container to have a cylindrical portion accessible from within the container and a slot accessible from the cylindrical portion and the exterior of the container. A housing fitted over the test port from the exterior of the container defines a chamber in line with the test port. A plug has a first portion sealable within the cylindrical portion of the test port, a second portion extending axially from the first portion for engagement in the slot when the first portion of the plug is sealed in the cylindrical portion, and a third portion extending axially from the second portion. A control rod is attachable to the third portion of the plug. The control rod forms a sealed fit with a portion of the chamber and is capable of movement along its longitudinal axis such that the first portion of the plug can be moved into the container to open the test port and into the cylindrical portion to seal the test port. A fluid passage is disposed in the housing in communication with the chamber between the container and the portion of the chamber forming a seal with the control rod. Fluid can pass through the fluid passage and the chamber about the control rod when moving to and from the test port.
