Garden Hose Fitting(https://www.ydvalve.com/product-usa/garden-hose-fitting/)
There are several types of garden hose fittings available, each with its own unique features and benefits. Here are some of the most common types of garden hose fittings:

Quick Connectors: These fittings allow you to quickly and easily attach and detach your garden hose from your outdoor spigot or other watering tools. They typically come in two parts - one attaches to the hose, and the other attaches to the spigot or other tool. Quick connectors are great for those who frequently switch between different watering tools.

Spray Nozzles: A spray nozzle is a garden hose fitting that attaches to the end of your hose and allows you to control the water flow and spray pattern. They are available in a variety of styles, including adjustable, fan, and shower. Some spray nozzles also have additional features such as a water shut-off valve or a soap dispenser.
