Description
300# Extra Heavy Black Malleable Iron 45° Elbow
300# extra heavy black malleable iron 45° elbows create a 45-degree change in direction between two male-threaded pipe ends, pipe nipples, valves, or compatible fittings of the same nominal size. Female NPT connections on both openings make these fittings suitable for demanding commercial, industrial, mechanical, fire-protection, maintenance, and repair applications.

How a 45° Pipe Elbow Works
A threaded 45° elbow has two female NPT connections arranged to create a gradual 45-degree change in direction. Compatible male-threaded pipe, pipe nipples, valves, or fittings are threaded into each opening, allowing the piping system to offset or redirect while maintaining the same nominal pipe size.

Frequently Asked Questions
What is a 300# black malleable iron 45° elbow used for?
It connects two compatible male-threaded components while changing the direction of the piping system by 45 degrees.
Does this elbow have female threads on both openings?
Yes. Both openings have female NPT threads for connection to compatible male-threaded pipe, pipe nipples, valves, or fittings.
Are both openings the same nominal pipe size?
Yes. This is a standard equal-size 45-degree elbow.
How is a 45° elbow different from a 90° elbow?
A 45° elbow creates a more gradual change in direction than a 90° elbow and is commonly used for offsets or layouts that do not require a right-angle turn.
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
