Asc 390028967 Gruvlok 7072 6x4 Grooved Concentric Reducer

Product Description

The ASC Engineered Solutions 390028967 is a Gruvlok 7072 grooved concentric reducer designed to transition between 6-inch and 4-inch grooved piping systems. Constructed from ductile iron with a painted finish, this fitting delivers the mechanical strength and corrosion resistance required in demanding piping installations. The concentric design keeps the pipe centerline aligned, which is critical in horizontal runs where consistent flow path alignment matters. Licensed pipefitters and mechanical contractors install this fitting as part of grooved mechanical joining systems in commercial and industrial applications.

This reducer is suited for commercial and industrial piping systems where grooved-end mechanical couplings are the joining method of choice. Typical installations include HVAC hydronic systems, fire protection piping, and process piping where a 6-inch-to-4-inch diameter reduction is required. The grooved ends mate directly with standard grooved couplings, eliminating the need for welding or flanging at the transition point.

Key Features

• Concentric reducer design maintains centerline alignment in horizontal and vertical piping runs
• Ductile iron construction provides high tensile strength and impact resistance
• Painted exterior finish offers baseline corrosion protection for above-ground installations
• Grooved ends are compatible with standard grooved mechanical coupling systems
• 6-inch x 4-inch size handles common large-to-mid-range pipe diameter transitions

Compatibility

Designed as an OEM-style grooved fitting for use with standard grooved mechanical coupling systems on 6-inch and 4-inch schedule pipe in commercial and industrial piping applications.

Installation Notes

Installation should be performed by a licensed pipefitter or qualified mechanical contractor familiar with grooved piping systems. Depressurize and drain the piping system fully before removing or installing any grooved fitting. Verify that pipe ends are properly rolled or cut-grooved to the correct groove specification before seating the coupling. Follow applicable mechanical codes including ASME and local authority having jurisdiction requirements.
