What are Cast Iron Radiator Fittings?


Cast iron radiator fittings are the components that connect your radiator to your plumbing system. These fittings include valves, pipes, and other hardware that allow hot water to flow through the radiator and distribute heat throughout your home.

Types of Cast Iron Radiator Fittings



Valves control the flow of hot water to your radiator. There are two main types of valves: manual and thermostatic. Manual valves are simple on/off switches, while thermostatic valves automatically adjust the flow of water based on the temperature in the room.


Pipes are used to connect your radiator to your plumbing system. There are several types of pipes, including copper, steel, and plastic. Copper and steel pipes are the most common, but plastic pipes are becoming more popular due to their ease of installation.

Radiator Feet

Radiator feet are used to support your cast iron radiator. They come in a variety of styles and sizes, and they can be made from cast iron or other materials like brass or aluminum.

Choosing the Right Cast Iron Radiator Fittings



When choosing cast iron radiator fittings, it’s important to make sure they are compatible with your radiator and plumbing system. Check the manufacturer’s specifications to ensure you are purchasing the correct fittings.


Cast iron radiator fittings come in a variety of styles, so it’s important to choose fittings that match the look of your radiator and your home. Consider the color, shape, and material of the fittings to find ones that complement your decor.
