Abstract
An apparatus and method for sealing a port of a distribution head in a fuel dispensing system. A plug has a head, flange and threaded shank. The flange extends radially beneath the head and includes a seal engagement surface. A sealing member is positioned upon the seal engagement surface. The port has NPT threads formed therein for engaging with the threads of the plug. When the plug is fully engaged with respect to the port, so as to be bottomed out, a seal is formed between the plug and port while the threads of the plug and port do not achieve an interference fit, to allow for easy removal of the plug.
