## Summary description

Unidelta reduced coupling for polyethylene (PE) pipes, nominal size 50 x 40 mm. Mechanical fitting designed to join pipes with different diameters, providing a stable transition between 50 mm and 40 mm PE lines. Suitable for water supply, irrigation and general low-pressure piping systems where durable PE connections are required.

## Long description

Unidelta reduced coupling 50 x 40 mm is a mechanical polyethylene (PE) pipe fitting designed to join PE pipelines of different diameters. It provides a stable, leak-resistant transition between a 50 mm main line and a 40 mm branch or continuation. Manufactured for use in low-pressure systems, this fitting is intended for potable water distribution, irrigation networks and general utility piping where a durable PE connection is required.
Advantages
The coupling is made to match the flexibility and chemical resistance of PE pipe systems while delivering consistent mechanical strength at the joint. Its reduced design ensures a compact connection with minimal flow disturbance. The fitting simplifies installation by allowing direct coupling between differing diameters without the need for complex adapters or additional welding, and it is compatible with standard PE pipe dimensions.
Suitable for
Domestic and municipal water supply lines
Irrigation and agricultural distribution systems
Low-pressure utility and service piping
Repairs and modifications where a diameter transition is required
Key specifications
Material: polyethylene (PE)
Connection: mechanical reduced coupling for two different diameters
Nominal sizes: 50 mm to 40 mm
Application pressure: suitable for low-pressure piping systems (typical PE water distribution and irrigation)
Typical compatibility: designed for standard PE pipe external diameters and wall thicknesses
How to use
Prepare pipe ends by cutting square and removing burrs or debris. Ensure pipes are clean and dry before assembly. Slide the coupling onto the larger diameter pipe and then insert the smaller diameter pipe into the opposite side until a secure fit is achieved. Follow standard installation practices for mechanical PE couplings, checking alignment and engagement depth. After assembly, inspect the joint visually and, where appropriate, perform a pressure test in accordance with system requirements to confirm leak-free performance.
Usage recommendations
Use the coupling in systems with compatible PE pipe dimensions and within the intended low-pressure range. Avoid exposure to temperatures and chemicals outside PE material limits, and protect the joint from prolonged UV exposure where required. For critical potable water installations or pressurized systems, follow local codes and testing procedures to ensure compliance and long-term reliability.
