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 fire protection, HVAC, or industrial process lines. It reduces flow from a 4 in to a 2 in line while maintaining a straight run, using ductile iron construction rated to 300 psi @ 150° F.

What are the specifications of the GRUVLOK 4 in x 2 in concentric reducer?

The GRUVLOK metal pipe straight concentric reducer (MPN 0390028629) is a grooved fitting in ductile iron, sized 4 in x 2 in. Its maximum operating pressure is 300 psi @ 150° F. This OEM part is designed for use with grooved-end pipe and couplings in commercial and industrial applications.

Where to buy a GRUVLOK concentric reducer worldwide?

3G Electric supplies the GRUVLOK concentric reducer (MPN 0390028629) to customers worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your site. Contact us for a quote and lead time on this ductile iron grooved fitting.

How to install a GRUVLOK grooved concentric reducer?

Installation follows standard grooved-pipe practices: lubricate the gasket, place it over the pipe end, insert the reducer, then slide the coupling housing over the groove and tighten bolts evenly to the manufacturer’s torque spec. Always verify alignment and pressure rating (300 psi @ 150° F) before system pressurization.
