German standard Angle valve with long nut and teflon seal

Brass angle valve is a type of valve commonly used in plumbing systems to control the flow of water. It is typically made of brass, which is a durable and corrosion-resistant material, making it suitable for use in water supply lines. The valve is called an "angle" valve because it is designed with an inlet and outlet that are perpendicular to each other, forming a 90-degree angle. This design allows the valve to be installed in tight spaces, such as behind toilets or under sinks, where a straight valve might not fit.

Brass angle valves are often used to connect water supply lines to fixtures like toilets, sinks, and washing machines. They usually have a handle that can be turned to open or close the valve, controlling the flow of water. The valve may also include a compression fitting or a threaded connection to attach to the water supply line.

Key features of brass angle valves include:

1. **Durability**: Brass is resistant to corrosion and can withstand high water pressure, making it a long-lasting material for plumbing fixtures.
2. **Compact Design**: The 90-degree angle allows for easy installation in confined spaces.
3. **Ease of Use**: The handle makes it simple to turn the water supply on or off.
4. **Versatility**: Brass angle valves can be used in a variety of plumbing applications, including residential, commercial, and industrial settings.
