Ductile iron concentric reducer coupling 3 inch to 2 inch grooved ends painted finish

Gruvlok

Gruvlok 390028447 Concentric Reducer 3"x2" coupling

SKU CH-84JY-6ANK3

Ductile iron concentric reducer joins 3 inch grooved pipe to 2 inch grooved pipe at 300 psi working pressure

  • Ductile iron construction resists corrosion and mechanical stress
  • Class 150 rating suits 300 psi at 150 °F service
  • Grooved ends on both sides enable fast, tool-free assembly
  • Concentric design keeps flow centred through the 3 in to 2 in transition
  • Painted finish adds surface protection for long installed life

Gruvlok Concentric Reducer 3"x2

This ductile-iron concentric reducer joins 3-inch grooved pipe to 2-inch grooved pipe in Class 150 systems. It is rated for 300 psi at 150 degrees F and suits Schedule 40 piping. The painted finish protects the fitting during handling and installation. It is intended for contractors assembling grooved mechanical piping networks.

Grooved joint installs with standard coupling tools

The grooved ends accept typical Gruvlok couplings so the reducer can be pressed into place without welding or threading. Misalignment of the pipe centrelines or insufficient gasket seating are the most common issues that cause leaks. Always verify that the groove dimensions match the coupling specification before tightening.

Class 150 pressure limit governs system design

The 300 psi rating at 150 degrees F sets the maximum operating envelope for this fitting. Higher temperatures or pressure spikes beyond the class rating will exceed the design allowance. The reducer does not alter the pressure class of the surrounding piping, so the whole assembly must remain within the Class 150 limit.

Questions about this item

How can I confirm the Gruvlok 390028447 concentric reducer is seated correctly after installation?

Verify the grooved ends are fully engaged in the coupling housings and the gasket is evenly compressed around the 3 in and 2 in pipe connections.

What components are included with the Gruvlok 390028447 reducer and what must be sourced separately?

The ductile iron reducer body is supplied; compatible grooved couplings, gaskets, bolts and Schedule 40 pipe must be purchased separately.

Which Gruvlok concentric reducer version matches a 3 in to 2 in grooved system rated for 300 psi at 150 Degrees F?

The 390028447 model is the Class 150 ductile iron painted reducer built for that exact size and pressure rating.
