Product Description

The GRUVLOK Metal Pipe Elbow is a grooved pipe fitting configured as a concentric reducer with a 12 in x 4 in fitting pipe size and a 7 in overall length (MPN 0390029577). This OEM component is designed for use in industrial piping systems requiring a change in pipe diameter.

Frequently Asked Questions

What is a GRUVLOK concentric reducer elbow used for?

A GRUVLOK concentric reducer elbow connects two pipes of different diameters in a grooved piping system, allowing a smooth transition from 12 in to 4 in. It is commonly used in industrial water, HVAC, and fire-protection applications where space constraints require a compact fitting.

What are the specifications of the GRUVLOK 12 in x 4 in reducer elbow?

This GRUVLOK grooved pipe fitting is a concentric reducer elbow with a 12 in x 4 in fitting pipe size and a 7 in overall length. The OEM part number is 0390029577. It is designed for metal piping systems requiring a diameter reduction in a single fitting.

Where to buy a GRUVLOK 12 in x 4 in reducer elbow worldwide?

3G Electric supplies and delivers the GRUVLOK 12 in x 4 in concentric reducer elbow (MPN 0390029577) worldwide. As a global industrial solutions provider, we handle full logistics and customs clearance to ensure the fitting reaches your facility, regardless of location.

How to install a GRUVLOK grooved reducer elbow?

Installation follows standard grooved-pipe practices: lubricate the gasket, place it over the pipe end, insert the reducer elbow, and secure with coupling housing and bolts. Ensure pipe ends are clean and properly aligned. Torque bolts to manufacturer specifications for a leak-tight joint.
