What device is used to distribute gas to multiple appliances in a gas supply line?

The device used to distribute gas to multiple appliances in a gas supply line is a manifold. A manifold functions by connecting multiple gas lines from a single source and allowing for the distribution of gas to various appliances, such as stoves, heaters, or water heaters. It effectively manages the flow and ensures that each appliance receives the required amount of gas for efficient operation.

In particular, a manifold is designed to withstand high pressure and is typically equipped with multiple outlets, making it versatile and practical for household or industrial applications. This feature distinguishes it from other devices that serve different purposes.

For instance, a regulator valve primarily controls the pressure of gas flowing from the supply line but does not distribute it to multiple points. A gas shutoff valve serves as a safety mechanism, allowing for the manual shutoff of gas flow in an emergency or maintenance scenario, but it doesn't manage multiple connections. A gas leak detector is used for safety purposes to detect any potential leaks in the gas lines, ensuring safety but not facilitating distribution.

Thus, the manifold is the appropriate choice for the distribution of gas to multiple appliances in a gas supply system.
