A street elbow is a 90° pipe fitting that changes the direction of flow in a piping system. What makes it different from a standard elbow is its thread configuration: one end has a male (external) thread, and the other has a female (internal) thread. This design lets you connect it directly to another threaded fitting, pipe, or valve without needing a separate nipple — saving space, reducing leak points, and simplifying installation.
At SS Flow Control, we manufacture street elbows in stainless steel 304, 316, and 316L. These materials resist corrosion, withstand high temperatures, and maintain their strength in demanding environments — oil and gas, chemical processing, water treatment, food and beverage, and pharmaceutical lines. Stainless steel is the standard choice when reliability and longevity matter.
Key facts
- 90° angle change with one male and one female threaded end
- Eliminates the need for a separate nipple in tight spaces
- Available as 45° street elbows on request
- Standard sizes 1/8" to 4" (DN6 to DN100), custom sizes available
- Every street elbow is checked for thread fit and pressure rating before shipping
Street Elbow vs. Standard Elbow — What's the Difference?
A standard elbow typically has two female (internal) threaded ends, or two socket weld ends. A street elbow has one male and one female end. This single difference changes how the fitting is used: a standard elbow needs a nipple or pipe stub to connect to another fitting, while a street elbow threads directly into the next component. That makes street elbows the go-to choice for compact assemblies, equipment connections, and anywhere you want to reduce the number of joints.
