Unidelta Reducing Coupling Compression Fitting

The Unidelta Reducing Coupling Compression Fitting is a high-quality mechanical connector designed to join two polyethylene (PE) pipes of different diameters quickly, securely, and without leaks. Made in Italy from premium polypropylene reinforced for UV and corrosion resistance, this reducing coupling delivers outstanding durability and long-term reliability in potable water, irrigation, and industrial pipeline systems.

Its precision-engineered compression mechanism ensures a tight, dependable seal without the need for heat fusion, adhesives, or specialised tools—making installation efficient and maintenance-free. The compact design allows for easy use in confined spaces while maintaining full flow performance and system integrity.

Ideal for adapting pipeline sizes during repairs, system upgrades, or network modifications, the Unidelta Reducing Coupling offers a robust and versatile solution for modern PE piping installations.
