## Long description

Crimp coupling Comap 50x40 DWZ (model 740MLX) red is a press-fit plumbing fitting designed to join two pipes with different diameters — 50 mm to 40 mm. Manufactured by Comap, this coupling features a red DWZ outer sleeve and a mechanical press joint that produces a reliable, leak-resistant connection when installed with compatible pressing tools. It is intended for professional use in potable water and heating systems where the pipe materials and dimensions match the coupling’s specification.
Advantages
The coupling provides a consistent mechanical connection that reduces the risk of leaks compared with traditional threaded or soldered joints when installed correctly. Its press-fit design allows for fast on-site installation, saving time on assembly and minimizing the need for hot works. The red DWZ sleeve offers clear visual identification of the fitting type and size, while the construction is suitable for standard installation pressures in domestic and light commercial water and heating circuits.
Suitable for
Joining a 50 mm pipe to a 40 mm pipe in plumbing and heating systems
Potable (drinking) water distribution when compatible pipe materials are used
Closed-loop heating circuits and radiator connections
Professional on-site press-fitting installations using compatible pressing tools
Key specifications
Connection sizes: 50 mm to 40 mm
Type: crimp / press-fit coupling with DWZ outer sleeve
Color: red (sleeve identification)
Application: potable water and heating systems
Compatibility: designed for use with matching pipe materials and press tools
How to use
Ensure the pipe ends are cut square, deburred and cleaned. Slide the crimp coupling onto the larger pipe end first and then align the smaller pipe into the opposite side until it reaches the internal stop. Use the appropriate pressing tool and jaw size for the specified connection diameters and follow the tool manufacturer’s instructions to perform the press operation. After pressing, verify the joint visually and, where required, perform a pressure test according to local plumbing standards to confirm leak-tightness.
Usage recommendations
Use only with pipe materials and dimensions compatible with the coupling. Employ the correct pressing jaws and calibrated pressing equipment. Do not use the fitting with damaged sleeves or deformed components. Follow applicable local codes and installation standards for potable water and heating systems.
