Description
300# Extra Heavy Galvanized Malleable Iron 45° Elbow
300# extra heavy galvanized malleable iron 45° elbows change the direction of a threaded piping system by 45 degrees. The female NPT connections provide a durable angled connection for demanding commercial, industrial, mechanical, fire-protection, maintenance, and repair applications where corrosion resistance and a galvanized finish are required.

How a Threaded 45° Elbow Works
A threaded 45° elbow has two female NPT openings positioned at a 45-degree angle. Each opening threads onto a compatible male-threaded pipe, pipe nipple, valve, or fitting, allowing the piping route to change direction gradually while maintaining a secure threaded connection.

Frequently Asked Questions
What is a 300# galvanized malleable iron 45° elbow used for?
It changes the direction of a compatible threaded piping system by 45 degrees.
Does this elbow have female threads on both ends?
Yes. ASC Figure 3162 has female NPT threaded connections on both ends.
Why use a 45-degree elbow instead of a 90-degree elbow?
A 45-degree elbow provides a more gradual directional change and may be useful where the piping layout does not require a full right-angle turn.
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 4" 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 elbow has female NPT threaded connections on both ends.
- 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 45-degree directional change is 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.
