Adapters are used to create a transition from one size to a smaller one in the pipeline section of heating or water supply systems. The adapter has a larger size with an internal thread and a smaller size with an external thread. The design of the body provides a special hexagon for easy grip with a wrench. This simplifies the installation process.
