Description
300# Extra Heavy Galvanized Malleable Iron 90° Street Elbow
300# extra heavy galvanized malleable iron 90° street elbows change the direction of a threaded piping system by 90 degrees while transitioning between a female NPT connection and an integral male NPT street end. The compact male-by-female configuration provides a durable right-angle connection for demanding commercial, industrial, mechanical, fire-protection, maintenance, and repair applications where corrosion resistance and a galvanized finish are required.

How a Threaded 90° Street Elbow Works
A threaded 90° street elbow has one female NPT opening and one integral male NPT end positioned at a right angle. The male street end threads directly into a compatible female-threaded fitting, valve, or equipment connection, while the female opening accepts a compatible male-threaded pipe, pipe nipple, valve, or fitting. This configuration creates a compact 90-degree turn without requiring a separate pipe nipple between two female-threaded components.

Frequently Asked Questions
What is a 300# galvanized malleable iron 90° street elbow used for?
It changes the direction of a compatible threaded piping system by 90 degrees while connecting a female-threaded component to a male-threaded component.
What connections does this street elbow have?
ASC Figure 3170 has one female NPT connection and one integral male NPT street connection.
What is the advantage of a street elbow?
The integral male street end can thread directly into a compatible female fitting, valve, or outlet, often eliminating the need for a separate pipe nipple and creating a more compact installation.
What is the benefit of the galvanized finish?
The galvanized finish provides added corrosion resistance compared with an unfinished black malleable iron fitting.
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 listings apply?
The fitting conforms to ASME B16.3, ASTM A197, and ASME B1.20.1 requirements. ASC lists its Class 300 malleable iron fittings as UL Listed.
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 female NPT connection and one male NPT connection.
- The selected variation determines the ASC item number, online selling price, estimated weight, and net cost.
- Confirm the nominal size and thread type of both mating components before ordering.
- Confirm that a 90-degree directional change and male-by-female street configuration are appropriate for the required piping layout.
- Confirm pressure, temperature, media compatibility, and application requirements before installation.
- Use an approved thread sealant suitable for the piping media and operating conditions.
- Avoid overtightening, which may damage the fitting or mating threads.
- Support connected piping properly to avoid excessive mechanical stress on the fitting.
- Installation should be completed by qualified personnel and comply with applicable codes and standards.
