Asc Engineered Solutions 390028769 Grooved Concentric Reducer

Product Description

The ASC Engineered Solutions 390028769 is a grooved concentric reducer designed for use in mechanical piping systems where a transition from a 5-inch pipe to a 3-inch pipe is required. Manufactured from ductile iron with a painted finish, this fitting is compatible with standard grooved pipe coupling systems. It provides a concentric reduction, keeping the pipe centerlines aligned, which simplifies layout and hanger placement in commercial and industrial installations. Licensed pipefitters and mechanical contractors rely on this type of fitting for fire protection, HVAC hydronic, and general industrial piping applications.

This reducer is suited for commercial and industrial piping systems using grooved mechanical joining methods. It is a direct bolt-on component that pairs with standard grooved couplings and housings without welding or threading. Typical installation scenarios include main-to-branch transitions in chilled water, heating water, or fire suppression piping. The painted exterior finish provides basic corrosion resistance during installation and in dry or indoor environments.

Key Features

• Concentric design keeps pipe centerlines aligned for simplified layout and support
• Ductile iron construction provides strength and durability in mechanical piping systems
• Painted exterior finish offers basic corrosion protection for indoor and dry environments
• Grooved end connections eliminate the need for welding or threading during installation
• 5-inch inlet to 3-inch outlet accommodates common main-to-branch pipe transitions

Compatibility

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

Installation Notes

This fitting is installed by licensed pipefitters or mechanical contractors as part of a grooved piping system. Depressurize and isolate the pipe section before installation and follow the coupling manufacturer torque and assembly guidelines for grooved joints. Inspect pipe ends for proper groove dimensions and freedom from burrs or damage before assembly. Installation should comply with applicable mechanical codes including ASME and local plumbing or fire protection standards.
