Construction & Applications
Malleable Iron Construction
Manufactured from malleable iron castings conforming to ASTM A197 for dependable strength and durability in threaded piping systems.
Street Pattern
The male x female connection allows the elbow to thread directly into another compatible female-threaded fitting, reducing the need for extra components.
90° Direction Change
The elbow creates a full right-angle turn in the piping run while maintaining a compact threaded assembly.
Why Use a Street Elbow?
More Compact Installation
A street elbow can connect directly into another female-threaded fitting, helping shorten the overall piping assembly where installation space is limited.
Fewer Components
Because one end is male threaded, a separate pipe nipple may not be required between the elbow and the adjoining fitting.
Typical Applications
Industrial & Mechanical Piping
- Industrial piping systems
- Mechanical piping
- Commercial installations
- Compact threaded assemblies
Common Services
- Water piping
- Gas piping
- Oil piping
- Fire protection systems
