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 in fire protection, HVAC, or industrial process lines. It reduces flow from a 5-inch to a 2-1/2-inch line while maintaining a 300 psi rating at 150°F.

What are the specifications of the GRUVLOK 0390028751 concentric reducer?

The GRUVLOK 0390028751 is a ductile iron concentric reducer with fitting pipe size 5 in x 2-1/2 in. It has a maximum operating pressure of 300 psi at 150°F. The manufacturer part number is 0390028751. It is a grooved pipe fitting for mechanical joining.

Where to buy a GRUVLOK 5 in x 2-1/2 in concentric reducer worldwide?

3G Electric supplies the GRUVLOK 0390028751 concentric reducer to customers worldwide. We handle full logistics, customs clearance, and delivery to your project site. Contact our team to place an order for this OEM-specified component.

How to install a GRUVLOK grooved concentric reducer?

Installation follows standard grooved coupling procedures: lubricate the gasket, place it over the pipe ends, and engage the coupling housing. Tighten bolts evenly to the manufacturer's torque specification. Always verify pipe alignment and pressure rating before system pressurization.
