Description
300# Extra Heavy Black Malleable Iron 90° Street Elbow
300# extra heavy black malleable iron 90° street elbows create a compact 90-degree change in direction between a female-threaded opening and a male-threaded pipe, valve, or compatible fitting. The male NPT x female NPT configuration allows one end of the fitting to thread directly into another female-threaded component, reducing the need for an additional pipe nipple.

How a 90° Street Elbow Works
A threaded 90° street elbow has one male NPT connection and one female NPT connection arranged at a right angle. The male end threads directly into a compatible female-threaded fitting, valve, or equipment connection, while the female end accepts a male-threaded pipe, pipe nipple, valve, or fitting. This compact configuration changes direction by 90 degrees while minimizing the number of threaded components required.

Frequently Asked Questions
What is a 300# black malleable iron 90° street elbow used for?
It changes the direction of a threaded piping system by 90 degrees while connecting a female-threaded component on the male end to a male-threaded component on the female end.
What connections does this street elbow have?
It has one male NPT connection and one female NPT connection of the same nominal pipe size.
How is a street elbow different from a standard 90° elbow?
A standard 90° elbow normally has female NPT threads on both openings. A street elbow has one male NPT connection and one female NPT connection, allowing the male end to thread directly into another female-threaded component.
What pressure class is this fitting?
This fitting is manufactured as a 300# / Class 300 extra heavy threaded malleable iron fitting.
What sizes are available?
Available product variations range from 1/4" through 3" nominal pipe size.
What standards and approvals apply?
The fitting conforms to ASME B16.3, ASTM A197, and ASME B1.20.1 requirements and is UL/ULC Listed and FM Approved.
Should thread sealant be used during installation?
Use an approved pipe-thread sealant or thread tape selected for the piping media, pressure, temperature, applicable codes, and manufacturer recommendations.
Important Ordering Notes
- Select the required nominal pipe size before adding the product to your cart.
- This street elbow has one male NPT connection and one female NPT connection.
- The selected variation determines the ASC item number, UPC, online selling price, weight, and net cost.
- Confirm the thread type, connection orientation, and nominal size of both mating components before ordering.
