Typically, OMSS sanitary pressure elbows have a pressure rating of approximately 10 bar. However, the specific pressure rating still depends on the elbow material and the selected gasket material.
Yes, you can customize various aspects of the sanitary including material, dimensions, sealing material, and surface finish to meet specific requirements for different pipeline connections.
Yes, OMSS sanitary union elbows are reusable. But you should note that the sealing gasket must be replaced before reusing it. From the perspective of daily maintenance, it is also recommended that you are better to replace the gasket every 6 or 12 months.
The angle selection for sanitary union elbows depends on the piping system configuration. A 90° union elbow achieves a greater fluid deflection angle but may increase a higher fluid resistance, making it suitable for short pipe. While a 45° union elbow provides a gentler deflection angle and lower flow resistance, it is ideal for long piping systems to minimize fluid impact during the direction changes.
What Is a Sanitary Union Elbow?
Typically, sanitary union elbows are distinguished from standard welded or clamp type sanitary elbow fittings. These are elbows with removable nuts but can provide a more secure seal than conventional clamp ones. Compared to standard elbows, they have thicker pipe walls and support repeated disassembly and replacement.
Sanitary Union Elbow Functions
Provide Detachable Connections For Pipelines
An important function of elbows is to connect different pipes and construct a complete piping system. Similarly, a key function of sanitary union elbows is that they provide a tight seal while also offering the flexibility for disassembly and replacement.
This feature significantly provides the convenience for the maintenance and cleaning during the use, reducing the cost of repairing pipelines. Additionally, you can extend their service life by regularly cleaning and replacing the sealing gaskets.
Change The Direction Of Fluid Media
Another function of sanitary union elbows is to change the flow direction of fluids within pipelines. Common union elbows are divided into 45° and 90° types. They enhance the space utilization when constructing piping systems.
The thickened wall design of sanitary union elbows also enables them to better withstand pressures generated during fluid flow and directional changes, ensuring the long term operational stability of your piping system.
Maintain Sanitary Conditions
For industries such as food and pharmaceuticals, another crucial function of sanitary union elbows is maintaining the cleanliness and hygiene during pipeline system operation.
Their inner and outer surfaces of sanitary union elbows are typically polished to achieve a low surface roughness, which reduces the possibility of liquid residue buildup and bacterial growth. Furthermore, these elbows are commonly constructed from 304/316L stainless steel and have food grade sealing gaskets, supporting CIP/SIP operations to further ensure safety and hygiene during use.
Structure of a Sanitary Union Elbow
The Elbow Body
This is the main body of a sanitary union elbow. Common materials for union elbows in sanitary applications include 304/304L/316L stainless steel to achieve superior corrosion resistance and higher hygiene standards.
The Sealing Gasket
Sealing gaskets are another critical component for enhancing the sealing performance of sanitary union elbows.
Materials commonly used for sealing gaskets in pharmaceutical and food applications include food grade rubber compounds such as EPDM and FPM. In terms of corrosion resistance, FPM withstands a broader range of corrosive substances. Regarding sterilization, EPDM supports steam sterilization cycles lasting up to 20 minutes.
The Nut
The nut is a key distinguishing feature between sanitary union elbows and standard sanitary elbows. We typically secure and install union elbows by tightening the nut, reducing the need for complex procedures like welding.
Like the elbow body itself, it is made of stainless steel to ensure consistent structural strength and corrosion resistance throughout the assembly.

How To Install a Sanitary Union Elbow?
- First, you need to insert the tube into the union elbow until it is firmly secured. Then, tighten the union elbow’s screw to hold the tube in place. The second pipe needs to be connected. Finally, you can connect the second pipe by following the same steps and tightening the union elbow’s other screw, too.
- After the connection, you can make it more secure by using a spanner. For example, use one spanner to hold the union elbow body in place and use the other to rotate the nut and tighten it further.
- Finally, you should make sure there are no gaps between the nut and the union elbow body, which means that the nut is completely sealed. The tightness of the nut is important for the union elbow to be able to handle higher pressure fluid.
Guide To Select a Proper Sanitary Union Elbow
Selecting the Right Material
When choosing a sanitary union elbow, selecting the appropriate material is a critical consideration. 304/304L or 316L, which material can you choose? Actually, this decision depends on your processing environment.
The main distinction between 304 and 316 series stainless steel lies in the inclusion of molybdenum. 316 contains a small amount of molybdenum, giving it superior corrosion resistance. The “L” series means lower carbon content, making it safer for high temperature sterilization environments.
To make you better understand, we can conclude that into the following sentences:
- 304 sanitary union elbow is suitable for general food processing environments.
- 304L sanitary union elbow is ideal for low-to-medium temperature cleaning in food and beverage applications.
- 316L sanitary union elbow is best suited for pharmaceutical applications with high hygiene requirements and steam sterilization needs.
Notice The Specifications And Sizes
Specifications and dimensions are also critical factors during selection. Before purchasing a sanitary union elbow, you must verify that its inner diameter and wall thickness are compatible with your existing piping system.
Additionally, you need to confirm the manufacturing standards of the selected union elbow. Internationally recognized standards include DIN, ISO, SMS, and others, which are equally essential for ensuring the union elbow fit seamlessly with your production line.
Choose According To The Pressure Level
The typical pressure tolerance range for sanitary union elbows is generally around 0-10 bar. These values are actually influenced by multiple factors, including the elbow wall thickness and the material of the sealing gasket.
Therefore, when selecting a model, you must first confirm the maximum pressure of the fluid within the piping system. Based on this, you can determine which union elbow is suitable and whether thicker walls are required to withstand higher pressures.
