2 Hollow Hexagonal PlugThe 2 Hollow Hexagonal Plug is a threaded pipe fitting designed to seal the end of a pipe or threaded connection. It features a hexagonal shape, making it easy to install or remove with a wrench. The plug has a hollow center, which allows it to act as a cap for empty or unused threaded pipe connections. This plug is commonly used in systems where sealing is needed but access to the interior of the pipe or fitting may be necessary later. Specifications
