Asc Engineered Solutions 390029148 Grooved Concentric Reducer

Product Description

The ASC Engineered Solutions 390029148 is a grooved concentric reducer designed for use in grooved piping systems where a transition from an 8-inch pipe to a 4-inch pipe is required. Manufactured from ductile iron with a painted finish, this fitting provides a centered, symmetrical reduction that maintains flow alignment along the pipe centerline. It is compatible with standard Gruvlok-style grooved couplings and fittings. Licensed plumbers, pipefitters, and mechanical contractors typically install this component in commercial and industrial fluid distribution systems.

This concentric reducer is suited for commercial and industrial piping installations including HVAC hydronic systems, fire suppression systems, and general fluid handling pipelines. It is used wherever a grooved pipe system requires a reduction from an 8-inch main line down to a 4-inch branch or downstream run. The painted ductile iron construction makes it appropriate for indoor and protected outdoor applications where corrosion exposure is moderate.

Key Features

• Concentric design maintains centerline alignment through the pipe size transition
• Ductile iron construction provides high strength and impact resistance
• Painted finish offers basic corrosion protection for standard service environments
• Grooved ends are compatible with standard grooved coupling systems
• 8-inch x 4-inch size suits large-diameter main-to-branch transitions

Compatibility

Designed as an OEM-style replacement and standard component for grooved piping systems requiring an 8-inch to 4-inch concentric reduction.

Installation Notes

Installation should be performed by a licensed pipefitter or plumber in accordance with applicable mechanical and plumbing codes. Depressurize and drain the piping system fully before removing any existing fittings or installing this reducer. Inspect grooved pipe ends for proper groove dimensions and condition before seating the coupling. Follow the coupling manufacturer torque and gasket seating procedures for the grooved connection at both ends.
