45° Elbow Configuration
Female NPT Inlet
One threaded opening accepts a compatible male NPT pipe, nipple, or fitting.
45° Elbow Body
The stainless steel elbow body redirects the piping run through a gradual 45-degree angle.
Female NPT Outlet
The second threaded opening connects to the adjoining compatible male NPT piping component.
Construction Details
These Class 150 threaded 45° elbows are manufactured in 304 and 316 stainless steel grades for piping applications requiring durable and corrosion-resistant construction.
The heavy-pattern fitting design conforms to ASTM A-351 and MSS-SP114, while the female NPT threaded connections conform to ASME B1.20.1. Fittings meet applicable chemical and mechanical property requirements.
Why Choose a Stainless Steel Threaded 45° Elbow?
Gradual Directional Change
- Changes piping direction by 45 degrees
- More gradual turn than a 90° elbow
- Female NPT connections on both ends
- Useful for angled offsets and routing changes
- Class 150 heavy-pattern construction
304 & 316 Stainless Steel
- Available in two stainless steel grades
- Corrosion-resistant construction
- ASTM A-351 material standard
- MSS-SP114 fitting standard
- Suitable for a variety of commercial and industrial piping applications
304 vs. 316 Stainless Steel
304 Stainless Steel
304 stainless steel is a widely used general-purpose stainless grade suitable for many commercial and industrial piping applications where corrosion resistance is required.
316 Stainless Steel
316 stainless steel is commonly selected where additional corrosion resistance is required. Confirm material compatibility with the intended media and service environment before ordering.
45° Elbow vs. 90° Elbow
45° Elbow
A 45-degree elbow provides a more gradual change in piping direction and is useful where the layout does not require a full right-angle turn.
90° Elbow
A 90-degree elbow provides a full right-angle directional change for tighter piping layouts.
Typical Applications
