Frequently Asked Questions

What is a GRUVLOK concentric reducer used for?

A GRUVLOK concentric reducer connects pipes of different diameters in grooved piping systems, typically for water, fire protection, or industrial fluid handling. It transitions flow from a 3 in line to a 2-1/2 in line, maintaining pressure up to 300 psi at 150° F.

What are the specifications of the GRUVLOK 3 in x 2-1/2 in concentric reducer?

This GRUVLOK concentric reducer is ductile iron, sized 3 in x 2-1/2 in, with a maximum operating pressure of 300 psi at 150° F. The manufacturer part number is 0390028462. It is a grooved pipe fitting designed for mechanical joining without welding.

Where to buy a GRUVLOK concentric reducer worldwide?

3G Electric supplies the GRUVLOK concentric reducer (MPN 0390028462) worldwide. As a global industrial solutions provider, we handle full logistics and customs clearance to deliver this ductile iron fitting to your site. Contact us for availability and lead time.

How to install a GRUVLOK grooved pipe reducer?

Installation requires aligning the grooved ends of the reducer with mating pipe grooves, then applying a gasket and coupling over the joint. Tighten bolts evenly to manufacturer torque specs. No welding or threading is needed, making it suitable for fast assembly in fire protection or industrial piping.
