What is the name of the connection between the chlorine tank and regulator?

The connection between the chlorine tank and regulator is called a yoke. A yoke serves as a crucial part of the system that allows the regulator to secure properly to the chlorine tank. It provides a stable and safe method for controlling the flow of chlorine gas, ensuring it is delivered to the treatment process at the correct pressure and rate. The design of the yoke facilitates a tight seal, reducing the risk of leaks, which is essential for both safety and effectiveness in water treatment operations. This connection is specifically designed to handle the unique properties of chlorine gas, which can be hazardous if not managed properly.

Other options such as adapter, nozzle, and connector do not accurately describe this specific type of connection. An adapter is typically used to join two dissimilar fittings or devices, while a nozzle refers to a device for directing or controlling the flow of liquid or gas, and a connector usually signifies a general term for linking two components without the specific safety features designed for gas systems like the yoke.
