Gruvlok® 0390009389 Red Rust Inhibiting Painted Ductile Iron Reducing Coupling, 3 in x 2-1/2 in, Grooved

The series 7010 reducing coupling makes it possible to directly connect two different pipe sizes, eliminating the need for two couplings and a reducing fitting. The specially designed reducing coupling gasket with a center rib assures proper positioning of the gasket and prevents the smaller pipe from telescoping into the larger during assembly.
