The Universal Series Reducing Coupling is ideal for the hybrid coupling of Polyethylene pipes (PELD, PEMD and PEHD), metal pipes, pipes of all material types such as PVC, PE, PP, lead, galvanised iron, steel, copper, both metric and imperial.
The coupling can be used in the distribution of pressurised fluids in irrigation and aqueduct systems. The reducing coupling does not require complete disassembly (push-in) and is designed and tested to guarantee a PN16 working pressure.
The metal inserts of the universal clamping ring ensure an effective grip on all types of surfaces and diameters. The special design of the gasket guarantees a perfect hydraulic seal in all applications: drinking water transport systems, in aqueducts and civil installations, in irrigation and gardening systems, fire-fighting systems, geothermal systems, sewage and industrial water conveyance and compressed air systems.
