Asc Engineered Solutions 390028660 Grooved Concentric Reducer

Product Description

The ASC Engineered Solutions 390028660 is a Gruvlok grooved painted concentric reducer designed for use in grooved piping systems where a transition from a 4-inch pipe to a 3-inch pipe is required. Constructed from ductile iron with a painted exterior finish, this concentric reducer provides a centered, inline flow path and resists corrosion in demanding mechanical piping environments. Weighing 2.58 pounds, the fitting is sized for straightforward integration into standard grooved coupling systems. It is typically installed by licensed pipefitters, mechanical contractors, or plumbing professionals working on commercial or industrial piping systems.

This reducer is suited for commercial and industrial mechanical systems that use grooved pipe connections, including HVAC hydronic piping, fire protection, and general fluid distribution. The concentric design maintains a centered pipe axis, making it appropriate for horizontal runs where alignment consistency is critical. The painted finish provides a baseline level of corrosion resistance suitable for interior mechanical room environments and similar applications.

Key Features

• Grooved end connections compatible with standard grooved coupling systems
• Concentric reducer design maintains centered pipe axis for inline flow transitions
• Ductile iron construction provides strength and durability in mechanical piping applications
• Painted exterior finish for baseline corrosion resistance
• Transitions from 4-inch to 3-inch pipe in a single fitting

Compatibility

Designed as an OEM-style replacement or new-installation grooved fitting for standard grooved piping systems accepting 4-inch by 3-inch concentric reducers.

Installation Notes

Installation should be performed by a licensed pipefitter or mechanical contractor in accordance with applicable mechanical and plumbing codes. Depressurize and drain the piping system fully before removing or installing any grooved fittings. Ensure grooved pipe ends are properly cut and rolled or cut-grooved to the correct groove specification before seating the coupling. Inspect the fitting and gasket seating area for damage prior to assembly.
