Abstract: The present invention is an inspection port that is self-locking and self-sealing when inserted in smooth, embossed, or corrugated metal jackets which contain an insulation layer around process equipment such as reactors, heat exchangers, distillation towers, storage tanks, and pipelines. The inspection port is made from an elastomeric material and includes a tubular body having an outer flange and two locking ridges which are positioned to form a short section for gripping non-corrugated metal and a long section for gripping corrugated metal.
