Product Description

The GRUVLOK Metal Pipe Straight: Concentric Reducer is a grooved pipe fitting (SKU 3G-OTH-460990) in ductile iron, sized 12 in x 6 in, with a maximum operating pressure of 300 psi @ 150° F.

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 diameter from 12 in to 6 in. It is used in fire protection, HVAC, and industrial water lines where ductile iron fittings handle pressures up to 300 psi @ 150° F.

What are the specifications of the GRUVLOK 12 in x 6 in concentric reducer?

This GRUVLOK concentric reducer (MPN 0390029627) is a grooved pipe fitting in ductile iron, sized 12 in x 6 in. It has a maximum operating pressure of 300 psi @ 150° F. 3G Electric supplies this genuine component for industrial applications worldwide.

Where to buy a GRUVLOK 12 in x 6 in concentric reducer worldwide?

3G Electric supplies the GRUVLOK 12 in x 6 in concentric reducer (SKU 3G-OTH-460990) to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. Contact us for availability and lead time on this genuine ductile iron fitting.

How to install a GRUVLOK grooved concentric reducer?

Installation follows standard grooved-pipe practices: lubricate the gasket, slide it over the pipe end, insert the reducer, and secure with coupling housing and bolts. Tighten bolts evenly to the manufacturer's torque spec. Always verify pressure rating (300 psi @ 150° F) matches system requirements.
