Doubling one pipe into many is what we know from the world of mechanical and automotive engineering. We know this pipe doubling technique with manifold or brass manifold. In automotive engineering, this channel is known as the intake manifold and the exhaust manifold. The two do look similar, however it turns out they have different roles in their work.
This comparison only explains the basic distribution concept, not the actual working function.
If you disassemble the engine, you will find engine parts whose function is to deliver the fuel or air mixture. This is a distribution manifold that usually appears to have a nickel or brass coating on its body. This brass manifold usually consists of a control valve with a valve cover which will later become part of the installation with the thermo electric head.
The manifolds also have flow meters or secure locking guards as inlets and outlets. The equipment accompanying the manifold is also multilayer with two colored ball valves and with a thermometer. The two valves are the automatic air vent valve and the drain valve with different handle colors.

Why Brass Manifold are Superior
We know that many heating systems use brass manifold rather than stainless steel manifold. These two materials appear to be equally strong and durable. However do you ever notice the difference of them when applied to machines? They have to distribute water supplies from heat sources to distribution lines but they show significant differences.
The manifold itself is the center of the heating system. This part of the machine should also have criteria that are not only good at helping to circulate hot water throughout the system. Moreover, to keep the machine durable. Well, brass manifold will be a part of the engine that has slightly superior criteria than stainless steel manifold.
Brass manifold and stainless-steel manifold are both durable, can withstand high temperatures, corrosion resistance, fire resistant, and provide aesthetic appearance. However, the brass manifold is easier to install than stainless steel manifold because lower hardness of the material. Then when the temperature changes, brass manifold has more compatible thermal expansion characteristics with brass pipes that people usually use. This can help reduce the risk of water leaks when installed properly.
Meanwhile, to prevent corrosion, stainless steel has sufficient chromium content. However, stainless steel has a different thermal expansion rate than the brass pipes that people usually use. This often makes the risk of water leaks even higher if installation is not handled carefully. Therefore, it would be wise if you use brass manifold as part of your machine that is durable and doesn’t leak easily.
Choose Brass Manifold for Various Purposes
We know that brass material comes from a mixture of copper and zinc. Objects around us such as plumbing pipes, bearings, musical instruments, gears, bullet casings, and keys come from brass. This material is durable, easy to install or use, perfectly bright in color, and resistant to heat. Many brass manifold manufacturers create products that are strong enough to survive in tough business competition.
However, customers often have difficulty choosing one of the best manifolds. All look the same according to factory molds for various purposes. Therefore, you need a little precision to choose one that best suits your current brass pipes.
Look at the Factory That Produces It
Companies that usually handle projects in the HVAC industry for heating connection systems are often more reliable. They definitely have superior products whose quality is a long-term investment. There is a prominent quality guarantee.
Pay Attention to the Manifold Wall Thickness
In general, brass manifold that has thick wall has longer corrosion resistance and a longer service life. The Legom company from China sells brass manifolds with a distance between manifolds of 255 mm and a distance between branches of 50 mm. This design supports a maximum working pressure of up to 16 bar, while flow capacity depends on the system design.
No Welding on the Body
Water distributors really rely on intact brass manifold so that there are no leaks during installation and daily use. You can use water temperature typically from 0°C up to around 110°C, depending on the system design. Installing this kind of manifold is also easy because it will directly integrate with pipes made of brass material too.
Don’t forget that when you want to install a manifold, you must pay close attention to the condition of the wall or media. If the media is not sturdy enough, it can make the manifold often wobble, which can cause slow leaks. Then, also provide a drain around the brass manifold installation area.
Legom’s Brass Manifold
Legom also produces brass manifold. Our manifold is pre-assembled distribution manifold, comprising the following components: control valves fitted with ergonomic handles, optimized for seamless integration with thermo-electric heads. Accompanied by precision-engineered flow regulating valves to ensure optimal performance. Engineered for compatibility with PEX fittings or versatile multilayer fittings for both the inlet and outlet.
This system is equipped with two automatic air vent valves to maintain system efficiency, alongside two drain valves featuring blue and red handles for easy identification and operation.
Installing this manifold is also quite easy and fast. Do call us to drop your first order as soon as possible. Then you will know the best quality of our products by using them in a proper way.
