ABSTRACT:
A corrosion-resistant test port kit is specially adapted to be retrofitted into existing duct work for use in testing or monitoring gases and vapors in an exhaust air transfer system that is designed to handle a wide range of potentially corrosive exhaust streams found in a wide variety of industrial applications. The apparatus provides the ability to install the test port kit in existing duct systems quickly and easily to monitor the gas stream without having to disassemble the duct system or interrupt its use for long periods. The test port kit has a corrosion-resistant threaded test port sleeve with a mounting shoulder, a corrosion-resistant shouldered washer that fits over the threaded test port sleeve and is disposed opposite the shoulder of the sleeve with the shouldered side of the washer facing away from the shoulder of the sleeve, a corrosion-resistant threaded nut to hold the test port in place in a hole in the duct system which is to be tested, a corrosion-resistant plug to block the test port when the test port is not in use for testing, and an installation tool.
