Asc Engineered Solutions 390028926 Grooved Concentric Reducer

Product Description

The ASC Engineered Solutions 390028926 is a grooved painted concentric reducer designed for use in Gruvlok-style mechanical piping systems. Manufactured from ductile iron and finished with a painted exterior for corrosion resistance, this fitting transitions a 6-inch grooved pipe down to a 3-inch grooved pipe in a single concentric reduction. Concentric reducers maintain the same centerline across both ends, which is critical in horizontal runs where alignment and drainage are important. Licensed pipefitters and mechanical contractors install this type of fitting as part of grooved mechanical coupling systems in commercial and industrial piping assemblies.

This reducer is suited for commercial and industrial mechanical piping applications including HVAC hydronic systems, fire protection distribution lines, and general fluid handling systems where grooved-end fittings are specified. The 6-inch by 3-inch size is a common transition point in branch and main configurations. It mates with standard grooved couplings and housings conforming to grooved piping system dimensions at both the large and small ends.

Key Features

• Concentric design keeps both pipe ends on the same centerline for clean inline transitions
• Ductile iron construction provides high tensile strength and impact resistance
• Painted exterior finish adds a layer of protection during storage and installation
• Grooved ends on both sides are compatible with standard grooved mechanical couplings
• 6-inch to 3-inch reduction handles significant diameter transitions in a single fitting

Compatibility

Designed as an OEM-style grooved concentric reducer for use with standard grooved mechanical coupling systems in commercial and industrial piping applications.

Installation Notes

Installation is performed by licensed pipefitters or mechanical contractors following the applicable mechanical and plumbing codes for the jurisdiction. Depressurize and drain the piping system fully before removing or installing any grooved fittings. Inspect the groove profile on mating pipe ends to confirm conformance to grooved coupling specifications before assembly. Do not overtighten coupling bolts beyond the coupling manufacturer's recommended procedure.
