What is Hydraulic Filter Housing?
In simple terms, a hydraulic filter housing refers to the outer casing that contains the hydraulic filter housing.
As such, a hydraulic filter housing plays an essential role in ensuring continuous filtration of the fluid.
This is by ensuring the other parts of the hydraulic filter functions appropriately.
As we shall see later in this guide, these parts function together to ensure proper filtration takes place.
Hydraulic Filter Housing Material
The material for a hydraulic filter housing is a critical part that you need to consider when selecting a hydraulic filter housing.
Remember, the proper functioning of your filter will depend on the housing material ability to hold the pressure.
Also, the material needs to withstand external factors such as the environment in which it is operating on.
However, some manufacturers can customize your filter housing material depending on the real elements.
Basically, there are three types of filter housing material available for your filter housing that we are going to discuss here.
· SS 316 &SS 304
SS 316 &SS 304 are both two grades of steel available for hydraulic filter housing material.
Each of them has a different composition.
Stainless steel filter housing
For instance, SS 304 constitutes 8% nickel and 18% chromium.
The advantage of SS 304 is that it is adaptable to high temperatures.
The ease of fabrication of SS 304 allows you to have a quality surface finish for your hydraulic filter housing.
SS 316 has 16% chromium, 10% nickel and 2% molybdenum.
Molybdenum is the one responsible for making the steel corrosion resistant.
The composition of SS 316 makes it heat resistant and durable.
Selecting this material for your hydraulic filter housing implies that there will be minimal metallic contamination.
· Carbon steel
Carbon steel hydraulic filter housing have high-quality carbon as its primary material.
The advantage you have with this type of material is that it is cheaper than the other material.

Through heat treatment, carbon steel can become stronger and harder.
The advantage of this is your hydraulic filter housing can withstand a considerable amount of pressure.
A hydraulic filter housing with such material is common in petrol and rubber filtration and wastewater treatment.
However, several characteristics may hinder its use as a hydraulic filter housing material.
First, if the content of carbon is higher than steel, it may lower the weldability.
This may have an impact on the joints which means you will have to replace your hydraulic filter housing.
Also, a higher carbon content on your hydraulic filter housing has an effect of lowering the melting point.
This may hurt your filter housing.
There are three types of carbon steel materials that you can select for your hydraulic filter housing.
That is mild or low-carbon steel, high-tensile steel,and higher-carbon steels.
Mild carbon steel contains a carbon content of between 0.05- 0.25%.
This type of carbon steel has a low tensile strength; however, carburizing allows you to increase the surface hardness.
The disadvantage of this type of carbon steel has a limitation of yield-point run out especially in cases where the material consists of two yield points.
High tensile carbon steels are carbon steels that have a low carbon content due to the availability of other alloying ingredients.
These ingredients increase the material wear and strength characteristics.
High carbon steels are those carbon steels that have a higher percentage of carbon content in them.
Such materials go through heat treatment to increase the carbon content to between 0.30- 1.70%.
Examples of such ingredients include silicon, manganese, nickel, and vanadium.
· UNS S32760 Filter Housing for Seawater
If you are planning on filtration of salty water, then this is the perfect hydraulic filter housing material for you.
It’s chemical composition allows for such filtration while inhibiting corrosion.
Remember, seawater filters are specially designed for salty water environments.
The composition includes Tungsten, 6% molybdenum, 25% chromium, 7% nickel and copper.
The other advantage you have is their high impact strength.
This allows for filtration without worrying about the fracture of the parts.
Parts of a Hydraulic Filter Housing
A quality hydraulic filter housing constitutes of different elements that work harmoniously to ensure efficiency.
Understanding these parts is therefore crucial in understanding a hydraulic filter housing.

Here is a look at each of these parts.
a) The hydraulic filter housing body
The hydraulic filter housing body is the outer part of the filter housing.
Remember, the choice of body material is vital to the success of the filter housing.
Most hydraulic filter housing bodies are of copper.
However, as we have seen, there are other materials available depending on the type of filtration that you are doing.
b) Cartridge couplers
The function of the cartridge coupler is to connect two filter cartridges concurrently thus doubling the filtration capacity.
Here, the connection enhances effectiveness and extends the length of the filter.
Most cartridge couplers are reusable; thus you don’t have to concern yourself with the cost.
c) Filter housing caps
The function of the filter housing caps is to prevent the fluid from leaking.
It also holds the filter elements in place thus ensuring maximum filtration of your fluid.
Even though these caps are small, they play an essential role in the filter housing.
You need always to ensure that you select a quality cap for your hydraulic filter housing cap.
A poor-quality cap may break quickly which leads to fluid leakages.
d) Filter housing sumps
The filter housing sumps refer to the bottom part of the hydraulic filter housing where unfiltered fluid collects during filtration.
They are generally tubular structures that allow for the collection of the fluid.
e) Pressure relief buttons
The purpose of these buttons is to regulate the pressure levels in the hydraulic filter housing.
Also, this is essential since it prevents the pressure exceeding the optimum level which may lead to rupture of the filter housing elements.
They are generally on the sides of the filter housing.
f) Hydraulic filter housing stand
The hydraulic filter housing stand is what holds the filter housing in position.
There are two types of filter housing stands available.
That is,a flexible hydraulic filter housing stand which allows for the movement of the filter housing to different positions.
Such a stand is typical in small but multiple applications.
You also have an inflexible hydraulic filter housing stand.
Such a stand does not move but instead is fixed at one point to allow for filtration purposes.
Inflexible stands are common in large and continuous applications.
Technical Specifications of the Hydraulic Filter Housing
There are several specifications that you need to check before purchasing a hydraulic filter housing for your application.
These specifications are critical in the proper functioning of your hydraulic filter housing.
Allow me to explain.
Hydraulic filter housing
· Pressure rating
Pressure rating is one of the considerations that you need to consider when selecting a hydraulic filter housing for your application.
It is critical in determining the level and efficiency of your filtration.
Selecting a hydraulic filter housing with a lower pressure rating than your application may lead to rupture of the filter elements.
This results in constant replacement of your filter which is costly in the long run.
On the other hand, you are selecting a hydraulic filter housing with a higher-pressure rating than your application will improper filtration.
The pressure will lower the flow of the fluid in your filter thus affecting the quality of filtration.
As a result, you need to select a hydraulic filter housing with the correct pressure ratings as your application.
· Working temperature
Working temperature also has a significant impact on the hydraulic filter housing.
The working temperature refers to the optimum temperature in which a hydraulic filter housing operates effectively.
Also, the effect of selecting a hydraulic filter housing with a lower working temperature is that it will affect the quality of filtration.
This happens in that a lower working temperature will lower the viscosity of the fluid during filtration.
As this happens, it will have an impact on the flow of the fluid thus affecting the quality of filtration.
A hydraulic filter housing with a higher working temperature also affects the quality of filtration.
It is therefore essential to select a hydraulic filter housing with the correct working temperature for your application.
Most hydraulic filter housings have a working temperature rating of between -22° to 250° F.
· Design configuration
How is the design configuration that important?
There is no standard design for the various applications that utilize hydraulic filter.
For instance, the design of specific applications can have an interior position for the filter.
In others, this position is on the outside while in others, it can be on the front.
Whichever the position is, the filtration process is still the same.
However, for compatibility, it implies that hydraulic filter housings have different designs.
It is therefore vital that you select a hydraulic housing filter that has a compatible design as your application.
· Opening and closing mechanism
The opening and closing mechanism of the hydraulic filter housing that you select needs to be simple and takes less time.
Such a mechanism is one that allows for either hand operation or basic tools such as clamps and springs.
At the same time, the mechanism should have safety precautions that will prevent any harm.
It should also not open by itself.
· Material type
There are different materials that you can have for your hydraulic filter housing.
As we have seen earlier, stainless steel, carbon steel,and UNS S32760 are some of the materials available for hydraulic filter housing.
Alternatively, customization of the material is another option available for your hydraulic filter housing.
However, in this case, you need professional guidance to come up with a material for your housing.
Several factors affect the selection of the hydraulic filter housing material.
They include the working environment and the cost of the material.
Selecting the right hydraulic filter housing material will have a positive impact on ensuring the efficiency and durability of your filtration system.
· Flow rate
The perfect hydraulic filter housing for your application is one that as the same flow rate as that of your application.
Besides, the flow rate affects the filtration quality of the fluid.
By selecting a hydraulic filter housing with the correct flow rate, it implies that the fluid flows appropriately.
This ensures complete filtration of your fluid.
Thus, ensure to match the flow rate of your application with that of your hydraulic filter housing.
· Inlet/Outlet connections
The inlet and outlet ultimately affect the choice of the hydraulic filter housing to choose.
Due to the different designs available, the point of outlet and inlet needs to be compatible with that of your application.
Also, the size of these connections needs to fit your application.
Selecting a filter housing with a smaller connection implies that it won’t fit your application thus cannot function.
