Unidelta Universal Transition Coupling Compression Fitting

The Unidelta Universal Transition Coupling Compression Fitting is a versatile and high-performance connector designed to join polyethylene (PE) pipes to pipes or fittings made from different materials—such as PVC, copper, steel, or other plastic systems. It provides a secure, leak-free transition between dissimilar pipe types, making it ideal for upgrades, repairs, and mixed-material installations.

Manufactured in Italy from premium, UV-stabilised polypropylene and corrosion-resistant components, this coupling ensures long-term durability and reliable sealing performance. Its flexible design allows it to compensate for slight variations in pipe outside diameter, making it extremely adaptable in the field. The Unidelta compression mechanism delivers a strong, mechanical joint that requires no welding, adhesives, or specialised tools—significantly simplifying installation.

Ideal for potable water networks, irrigation systems, and general plumbing applications, the Unidelta Universal Transition Coupling offers an efficient solution for connecting modern PE pipes to legacy or alternate piping materials.
