- Product Description:
- ● A stainless steel 45 degree elbow is a short piece of pipe with a 45-degree angle and female threads on either end.
- ● It is a 45-degree-angled pipe with internal threads, unlike a 90 elbow, which has a 90-degree bend.
- Used for:
- ● A 45 pipe elbow is used to change the direction of a pipe system by 45 degrees.
- ● Often used to connect two pipes or two fittings with male threads at a 45-degree angle.
- Advantage:
- ● Provides a gentler change in flow direction compared to a 90-degree elbow, resulting in reduced turbulence and pressure drop.
- To Install:
- ● Thread the female threaded ends onto male threads of the same size.
- Item Sizing:
- ● A 45-degree threaded elbow size is based on the size of the thread it will connect to.
- ● For Example, A 1" 45 pipe elbow will have a 1" female thread and will install onto a 1" male thread.
- Also referred to as:
- ● 45 ell.
- ● Plumbing 45.
- ● 45 degree elbow plumbing.
- Other Options:
- ● Another option is a 90 Elbow, which is also an elbow fitting except it has a 90-degree bend.
- ● Other options include Street Elbows, which are 90-degree pipe fittings.

- Materials of Construction:
- ● Manufactured with Stainless Steel 304 & 316
What is a 45 Elbow Fitting?
A 45 degree elbow is an angled pipe fitting used to add a 45-degree angle to a piping system. It is a short piece of pipe bent at a 45-degree angle, with internal threads on either end of the elbow bend. It is used to join two male threaded fittings or two pipe lengths at a 45-degree angle. They are often used in piping systems where straight runs are not possible. They are used to enable the piping to avoid obstacles and to change directions. This more gradual angle of the 45 degree bend is gentler than the right angle of a 90-degree elbow, which allows for a smoother flow of fluid with less turbulence and a reduced pressure drop. These 45-degree pipe fittings are made from high-grade Stainless steel 304 and 316, making them strong, robust, and corrosion-resistant. These angled elbows are used in industrial piping systems, including in HVAC, plumbing, and gas, to help avoid obstructions or to fit into small spaces.
45 Elbow vs 90 Elbow
| Characteristic | 45-degree elbow | 90-degree elbow |
| ● Angle | Gradual smooth 45° turn | Sharp right angle 90° turn |
| ● Resistance | Low resistance, low turbulence | Higher resistance, higher turbulence |
| ● Pressure | Small pressure drop | Higher pressure drop |
| ● Space | The bend requires more space | The bend fits into smaller spaces |
| ● Applications | High-speed fluids, where a smoother flow is required | Sharp corners, where a compact layout is required |
- Use a 45-degree elbow when energy efficiency matters and a smooth flow is required, especially in applications carrying fluids at higher speeds.
- Use a 90-degree elbow when space is tight or a sudden directional change is required, despite the higher drop in pressure.
