Product Overview
HENGSEN 180° Copper Return Bends, also known as copper U-bends, connect two parallel runs of compatible copper tubing through a 180-degree turn. Their U-shaped profile is designed for refrigeration and air-conditioning pipework that requires a return connection.
This range includes 21 size options from 8 to 67 mm, with wall thicknesses from 0.8 to 1.8 mm depending on the selected size. Each variant combines a specific connection size and wall thickness, making selection straightforward for new installations and replacement work.
Key Features
- 180-degree return connection: A U-shaped bend for reversing the direction of a copper pipe run.
- Copper construction: For connection to compatible copper tubing.
- Equal-size socket ends: Both ends use the same listed connection size.
- 21 size options: Choose from sizes ranging from 8 to 67 mm.
- Clearly specified wall thickness: Each variant identifies its size and corresponding wall thickness.

All measurements are in millimeters. The first number identifies the listed connection size, and the second identifies the wall thickness. These values are not the distance between the two ends, the overall dimensions or the bend radius.
Applications
- Refrigeration and air-conditioning copper pipework.
- Cold room and commercial refrigeration installations.
- Return connections between compatible parallel copper tubes.
- Replacement of existing U-bends with matching size and dimensional requirements.
Choosing the Correct Return Bend
Match the connection size and wall thickness to your piping specification. Sizes such as 22 and 22.23 mm, 25 and 25.4 mm, or 41.28 and 42 mm are separate options and should not be treated as interchangeable without checking the fit.
For a return bend, the distance between the two tube centerlines is also important. Confirm socket fit, center-to-center spacing and overall dimensions for your selected size before ordering, particularly when replacing a fitting between fixed tube ends.
Installation
Have a qualified installer confirm the jointing method and suitability for the system’s pressure, temperature and refrigerant. Prepare and join the tubing according to the installation procedure, then test the completed pipework before commissioning.
