When it comes to piping systems, elbows are essential components that allow for the smooth change of direction in the pipes. Whether you’re working on plumbing, HVAC, or other industrial systems, choosing the right elbow fitting is critical for system efficiency and durability. Among the various types of elbow fittings, street elbows and regular elbows are commonly used, but they serve different purposes. In this blog, we will explore the differences between street elbow vs regular elbow and help you determine which one suits your specific needs.
What is a Regular Elbow?
A regular elbow is a standard fitting designed to change the direction of a pipe. It is commonly used in a wide range of plumbing and piping systems to connect two pipes at an angle (typically 45° or 90°). These fittings are made to fit two pipes at each end, which are either threaded or welded. Regular elbows are typically used in situations where two sections of pipe need to be joined with a uniform connection on both sides.
Regular elbows are manufactured in various materials, including stainless steel, carbon steel, and other alloys, depending on the application’s needs. They are often used in straight runs where a simple directional change is needed.

Key Characteristics of Regular Elbow:
- Two End Connections: Regular elbows have two ends, both of which need to be connected to pipes.
- Standard Design: Ideal for simple 90° or 45° directional changes in piping systems.
- Variety of Materials: Available in a wide range of materials based on industry requirements.
What is a Street Elbow?
A street elbow, on the other hand, is a special type of elbow fitting that is designed with one male threaded end and one female threaded end. This design allows for a more compact connection, typically used when a pipe needs to be connected directly to a threaded pipe. The term “street elbow” refers to its ability to connect directly to a “street fitting” or pipe without the need for a separate coupling.
Street elbows are particularly useful in tight spaces where adding another coupling or fitting may be inconvenient or impractical. They are commonly found in situations where a system needs to be assembled with limited space or in installations where flexibility is required.

Key Characteristics of Street Elbow:
- Male and Female Threaded Ends: One side is male and the other side is female, offering a direct connection to threaded pipes.
- Compact Design: Helps save space and simplify installations in tight areas.
- Used in Special Applications: Ideal for situations where a single connection needs to be made, such as in plumbing systems.
Street Elbow vs Regular Elbow: Key Differences
Feature | Street Elbow | Regular Elbow |
---|---|---|
Connection Type | One male and one female threaded end. | Two ends that are usually welded, threaded, or flanged. |
Installation Requirements | Direct connection to a threaded pipe without additional fittings. | Requires two pipe connections and may need a separate fitting (e.g., coupling). |
Space Efficiency | More compact and space-efficient, ideal for tight spaces. | Requires more space due to the need for additional fittings or couplings. |
Application | Often used in plumbing, gas lines, and other systems requiring threaded connections. | Commonly used in standard piping systems for various applications, like HVAC, water systems, etc. |
Pipe Connections | Used in threaded pipe systems for direct connection. | Can be welded or threaded onto pipes, offering more flexible connection options. |
Flexibility | Less flexible, designed primarily for threaded connections. | More versatile, can be used for welding, threading, or flanging. |
Material Availability | Available in various materials like brass, copper, steel, etc. | Available in a wider range of materials, including stainless steel, carbon steel, alloy steel, etc. |
Durability | Generally durable for low-pressure systems but may be less suitable for high-stress applications. | Highly durable, suitable for both low and high-pressure systems, depending on material. |
Cost | Typically more affordable due to its simpler design. | Generally costs more due to versatility and material options. |
Size Options | Available in standard sizes for common threaded pipe connections. | Available in a wide range of sizes, from small to large diameters. |
Installation Complexity | Easier to install in tight spaces or where a single fitting is needed. | Requires more time for installation as both ends need to be secured to pipes. |
Conclusion
In conclusion, both street elbows and regular elbows play vital roles in piping systems, but their specific applications and advantages make them suited for different scenarios.
- If you’re dealing with tight spaces or need a quick, direct connection between two threaded pipes, the street elbow is the ideal choice. Its compact design and simplicity allow for space-efficient installations, making it perfect for plumbing, gas lines, and other threaded systems.
- On the other hand, regular elbows offer greater versatility and can be used in a wider range of piping systems, including those requiring welding or flanged connections. They’re more suited for larger-scale industrial applications where flexibility and strength are needed.
Ultimately, the decision between street elbow vs regular elbow comes down to your specific needs—whether you prioritize ease of installation in constrained spaces or require a versatile fitting for a variety of piping connections. By understanding the key differences, you can choose the right elbow fitting for your piping system, ensuring efficient, reliable, and durable performance.
