45° Elbow Configuration
4" Female NPT Connection
One end features a precision-machined 4" female NPT connection for installation with a compatible male-threaded pipe, nipple, fitting, valve, or equipment connection.
45° Direction Change
The elbow redirects the piping system by 45 degrees, providing a gradual change in direction for offsets and angled piping layouts.
4" Female NPT Connection
The opposite end also features a 4" female NPT connection for joining another compatible 4" male-threaded component.
Construction Details
Midland 4" Red Brass 45° Elbows are manufactured from premium red brass to provide dependable durability and corrosion resistance in demanding fluid handling applications.
Precision-machined female NPT threads on both ends provide secure engagement with compatible male-threaded components when installed using accepted piping practices.
The 45° configuration provides a smoother change in direction than a 90° elbow and is useful for offset piping runs or routing around nearby equipment and obstacles.
Why Choose a 45° Elbow?
Gradual Direction Change
- Changes piping direction by 45 degrees
- Useful for offset piping layouts
- Provides a gentler transition than a 90° elbow
- Helps route piping around equipment or obstacles
- Suitable for new installations and repairs
Red Brass Construction
- Excellent corrosion resistance
- Good resistance to dezincification
- Dependable mechanical strength
- Suitable for compatible commercial and industrial systems
- Designed for long-term threaded service
NPT Threaded Connections
4" Female NPT x Female NPT
Both ends use 4" female NPT threads for connection to compatible 4" male NPT pipe, nipples, fittings, valves, or equipment connections.
Thread Sealing
Use an appropriate thread sealant or PTFE tape on mating male NPT threads according to the system media, piping material, and installation requirements.
Typical Applications
Plumbing & HVAC
- Large-diameter threaded plumbing systems
- HVAC piping
- Mechanical rooms
- Utility piping
- Offset pipe routing
Industrial & Fluid Handling
- Industrial piping systems
- Process piping
- Fluid handling equipment
- Equipment connections
- Compatible general-purpose piping systems
Size Selection
This listing is specifically for a 4" Midland Red Brass 45° Elbow.
Confirm that both mating components use compatible 4" male NPT threads before ordering and verify that a 45-degree directional change matches the required piping layout.

Our pipe and fitting specialists can help review your 4" NPT connection requirements, 45° piping layout, mating components, system media, pressure, temperature, and material compatibility before you order.

What size is this elbow?
This listing is specifically for a 4" Midland Red Brass 45° Elbow.
What material is the elbow made from?
The fitting is manufactured from red brass.
What type of connections does it use?
It features 4" female NPT threaded connections on both ends.
What angle does this fitting provide?
This elbow changes the direction of the piping system by 45 degrees.
Why use a 45° elbow instead of a 90° elbow?
A 45° elbow creates a more gradual directional change and is useful for offsets, angled piping runs, and routing around nearby equipment.
Does this elbow reduce pipe size?
No. This is a 4" equal-size elbow with 4" connections on both ends.
Why use red brass?
Red brass provides dependable mechanical strength along with excellent corrosion and dezincification resistance in compatible piping systems.
Should thread sealant be used?
Use an appropriate thread sealant or PTFE tape on the mating male NPT connections according to the application requirements.
What are these elbows commonly used for?
Typical applications include plumbing, HVAC, industrial piping, process piping, mechanical systems, utility piping, and compatible fluid handling systems.
What should I verify before ordering?
Confirm the 4" nominal pipe size, mating male NPT threads, required 45-degree direction change, system pressure, temperature, media compatibility, and installation requirements.
Important Ordering & Installation Notes
