## Summary description

Unidelta reducing coupling for polyethylene (PE) pipes, model UN601163, connecting 63 mm to 50 mm pipe diameters. Designed for joining PE pipes with a stepped diameter change, this mechanical fitting provides a secure transition between larger and smaller pipe sections. Suitable for water distribution, irrigation, and underground PE pipeline installations where reliable diameter reduction is required.

## Long description

Unidelta reducing coupling PE 63x50 is a mechanical polyethylene (PE) fitting designed to connect a 63 mm PE pipeline to a 50 mm PE pipeline. The coupling provides a stepped diameter transition without the need for complex tools or heat fusion, enabling a compact and reliable connection in water distribution, irrigation systems, and buried PE networks where a controlled reduction in pipe size is required.
Advantages
The reducing coupling offers a robust, leak-resistant connection between larger and smaller PE pipes while maintaining alignment and flow integrity. Its design supports quick installation and reduces on-site preparation compared with thermofusion methods. Constructed for compatibility with standard PE pipe dimensions, the fitting is suitable for use in environments that require corrosion-resistant components and long-term performance in underground conditions.
Suitable for
 Water distribution mains and branch lines
 Irrigation systems for agriculture and landscaping
 Underground PE pipeline installations and repairs
 Transitions between mains and service pipes in residential or commercial networks
Key specifications
 Material: polyethylene-compatible mechanical fitting suitable for PE pipes
 Connection sizes: one end for 63 mm outer diameter pipe and the other for 50 mm outer diameter pipe
 Type: reducing (stepped) coupling for diameter transition
 Intended use: potable and non-potable water distribution, irrigation, and buried pipelines
 Installation method: mechanical joining without heat fusion
How to use
Prepare both pipe ends by cutting squarely and removing burrs or debris. Ensure pipe outer diameters match the specified sizes and that pipe ends are clean and dry. Insert the 63 mm pipe end into the larger side of the coupling and the 50 mm pipe into the smaller side, following the manufacturer’s alignment marks if present. Apply even axial force until pipes reach the required insertion depth; secure any external clamps or fastening elements if the fitting design requires them. After installation, verify alignment and perform a pressure test according to local regulations to confirm a leak-free joint.
Usage recommendations
Use the coupling with PE pipes that meet relevant dimensional and quality standards. Avoid excessive axial loads on the joint during backfilling and provide adequate bedding and compaction for buried installations. When used in potable water systems, follow local potable water installation standards and disinfect the pipeline as required before commissioning.
