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 configuration allows one end of the elbow to thread directly into another female fitting, helping reduce the number of components in the assembly.
Hot-Dip Galvanized Finish
The galvanized coating conforms to ASTM A153 and provides additional protection against rust and corrosion in moisture-prone and outdoor installations.
Why Use a Street 45 Elbow?
Compact Connection
The male-threaded end can often replace a separate nipple, allowing the elbow to connect directly into a female fitting and shortening the overall piping assembly.
Gradual Directional Change
The 45-degree angle provides a less abrupt change in direction than a 90-degree elbow and is useful for offsets and tighter routing around equipment or structural obstacles.
Typical Applications
Commercial & Mechanical Piping
- Commercial plumbing systems
- Mechanical piping
- Water distribution
- General utility piping
- Compact threaded pipe offsets
Galvanized Applications
- Outdoor piping
- Moist environments
- Water-service applications
- Industrial installations
- General galvanized piping systems

Frequently Asked Questions
What is a street 45 degree elbow?
A street 45 is a 45-degree elbow with one male threaded end and one female threaded end.
How is a street 45 different from a standard 45 elbow?
A standard threaded 45-degree elbow typically has female connections on both ends. A street 45 has one male and one female connection, allowing it to thread directly into another female fitting.
Why use a street elbow instead of an elbow and nipple?
The male end can often replace a separate nipple, reducing the number of components and shortening the overall piping assembly.
What type of connections does this fitting use?
The fitting uses one male NPT connection and one female NPT connection.
Why choose a 45 degree elbow instead of a 90 degree elbow?
A 45-degree elbow provides a more gradual change in direction and can be useful for offsets or piping layouts where a full 90-degree turn is not required.
Why choose a galvanized street elbow?
The hot-dip galvanized finish provides added resistance to rust and corrosion in installations exposed to moisture or outdoor conditions.
What standard applies to the galvanized coating?
The supplied product information states that hot-dipped galvanized fittings conform to ASTM A153.
What thread standard applies?
NPT threads conform to ASME B1.20.1.
Is this fitting UL Listed and FM Approved?
Yes. The supplied product information states that Class 150 fittings are UL Listed and FM Approved at 300 PSI.
Does the supplied information include lead-compliance requirements?
Yes. It states that galvanized fittings meet ANSI/NSF 61-4 Annex G and CA AB1953 with less than 0.25% lead.
