The grooved concentric reduction is an essential component for installations that need transitions between pipes of different diameters while maintaining hydraulic continuity and mechanical strength. The grooved system allows a quick, reliable and reversible connection, perfect for installation or maintenance work.
Thanks to its UL/FM certification, the reduction is particularly suitable for fire protection, HVAC and industrial water distribution systems. It is compatible with water- and glycol-based fluids up to a concentration of 15 percent.
