Description
Domestic Wrot Copper x Copper Long Turn 90° Elbow
Domestic wrot copper x copper long-turn 90-degree elbows provide a smooth right-angle change in direction between two equal-size copper-tube runs. The two female copper sweat sockets accept properly sized copper tube, while the longer-radius pattern creates a more gradual directional change than a standard short-radius 90-degree elbow.
Select the required nominal copper tube size from the product options above. The selected variation determines the Cello item number, online selling price, shipping weight, cost, and other size-specific product information.

How a Copper Long Turn 90° Elbow Works
Each female copper sweat socket fits over properly sized copper tube. After both tube ends and fitting sockets are cleaned and prepared, the joints are assembled with approved flux and soldered or brazed. The long-turn pattern produces a smoother 90-degree directional change than a standard short-radius elbow.
Long Turn vs. Standard 90° Elbow
Long Turn 90° Elbow
- Changes direction by 90 degrees
- Uses a larger bend radius
- Creates a smoother directional change
- Useful where reduced turbulence is preferred
Standard 90° Elbow
- Changes direction by 90 degrees
- Uses a more compact short-radius pattern
- Fits into tighter installation spaces
- Commonly used at corners and equipment connections
Common Applications
Plumbing and Mechanical Systems
- Potable-water piping
- Residential plumbing systems
- Commercial plumbing installations
- Mechanical-room piping
- Heating-system piping
- Copper distribution piping
HVAC and Equipment Connections
- Air-conditioning piping
- Refrigeration systems
- Heat-pump installations
- Equipment connections
- Vertical and horizontal transitions
- Maintenance and retrofit work
Installation Guidance
- Confirm the required nominal copper tube size before installation.
- Clean and prepare both copper tube ends and fitting sockets properly.
- Use approved flux, solder, brazing alloy, and joining procedures for the application.
- Insert each tube fully into the fitting socket before joining.
- Align the piping correctly before heating the joints.
- Allow sufficient space for the larger long-turn radius.
- Protect nearby valves, seals, insulation, and equipment from excessive heat.
- Support connected piping to avoid mechanical strain on the elbow.
- Pressure-test and inspect completed joints before placing the system into service.

Frequently Asked Questions
What is a copper long-turn 90-degree elbow used for?
It changes the direction of an equal-size copper-tube run by 90 degrees using a larger, more gradual bend radius than a standard short-radius elbow.
Are both connections the same size?
Yes. This product has equal-size female copper sweat sockets on both ends.
Does the elbow fit over copper tube?
Yes. Both female sweat sockets fit over properly sized copper tube.
Is this a long-turn elbow?
Yes. The WP7LT series is a long-turn copper x copper 90-degree elbow.
How is this different from a standard 90-degree elbow?
A long-turn elbow uses a larger bend radius for a smoother directional change. A standard 90-degree elbow uses a more compact short-radius pattern.
How is the elbow installed?
The copper tube ends and fitting sockets are cleaned, prepared with approved flux, assembled, and soldered or brazed according to accepted procedures and applicable codes.
Is this a domestic copper fitting?
Yes. This product is listed as a domestic wrot copper pressure fitting.
Who manufactures this elbow?
This product is manufactured by Cello Products.
Can it be used in potable-water systems?
It may be used in compatible potable-water systems when installed according to applicable codes, standards, manufacturer requirements, and approved joining procedures.
Can it be used for refrigeration or HVAC piping?
It may be used in compatible HVAC and refrigeration systems when the material, size, joining procedure, pressure, temperature, and system requirements are appropriate.
Is this the same as a street elbow?
No. This copper x copper elbow has two female sweat sockets. A street elbow has one male fitting end and one female copper sweat socket.
Important Ordering Notes
