Frequently Asked Questions

What is a GRUVLOK eccentric reducer used for?

A GRUVLOK eccentric reducer connects pipes of different diameters while maintaining a flat bottom to prevent air pockets in horizontal piping systems. It is commonly used in HVAC, fire protection, and industrial process lines where smooth flow transition is critical.

What are the specifications of the GRUVLOK 3 in x 1-1/2 in eccentric reducer?

This GRUVLOK eccentric reducer has a fitting pipe size of 3 in x 1-1/2 in, is made of ductile iron, and is rated for a maximum operating pressure of 300 psi @ 150° F. The manufacturer part number is 0390031995.

Where to buy GRUVLOK eccentric reducers worldwide?

3G Electric supplies GRUVLOK eccentric reducers worldwide, handling full logistics and customs clearance. As a global industrial solutions provider, we source this OEM part across 14 departments, including combustion, pumps and controls, to deliver the right fitting for your system.

How to select the right GRUVLOK eccentric reducer for a system?

Select a GRUVLOK eccentric reducer by matching the pipe sizes (inlet and outlet), pressure rating (300 psi @ 150° F for this model), and material (ductile iron) to your system's requirements. Ensure the grooved ends are compatible with your coupling style for a leak-free joint.
