Frequently Asked Questions

What is a GRUVLOK concentric reducer used for?

A GRUVLOK concentric reducer connects two different pipe sizes in a grooved piping system, reducing flow from 1-1/2 in to 1 in. It is used in fire protection, HVAC, and industrial process lines where ductile iron fittings with a 300 psi @ 150° F rating are required.

What are the specifications of the GRUVLOK 0390028264 concentric reducer?

The GRUVLOK 0390028264 is a ductile iron concentric reducer with fitting pipe size 1-1/2 in x 1 in. It has a maximum operating pressure of 300 psi @ 150° F. The manufacturer part number is 0390028264. 3G Electric supplies this genuine grooved fitting for industrial applications.

Where to buy a GRUVLOK concentric reducer worldwide?

3G Electric supplies the GRUVLOK concentric reducer worldwide, handling logistics, customs, and delivery to your site. As a global industrial solutions provider, we source genuine components like this 1-1/2 in x 1 in ductile iron fitting across 14 departments, including pumps and controls.

How to install a GRUVLOK grooved pipe reducer?

Installation follows standard grooved coupling procedures: lubricate the gasket, place it over the pipe ends, and tighten the coupling bolts evenly. Ensure pipe ends are clean and the reducer is aligned. 3G Electric can provide technical support for proper selection and installation of this 300 psi rated fitting.
