Asc Engineered Solutions 306059205 Flanged Reducer 4x3 in

Product Description

The ASC ENGINEERED SOLUTIONS 306059205 is a flanged concentric reducer fitting designed for piping systems that require a centered, symmetrical transition between a 4-inch and 3-inch pipe diameter. Constructed from black cast iron, this domestic-made fitting delivers the durability and mass required in industrial, commercial, and heavy-duty plumbing applications. The concentric design keeps the pipe centerlines aligned, which simplifies installation in horizontal runs where consistent flow alignment is critical. At 31.10 pounds, the fitting reflects the robust wall thickness typical of cast iron flange work. Licensed plumbers and pipefitters working on process piping, fire suppression, or draining systems will find this fitting suited to their standard flanged assemblies.

This reducer is intended for flanged piping systems where a 4-inch line reduces to a 3-inch line while maintaining centerline alignment. The flanged connection style allows for bolted assembly and disassembly, making it appropriate for systems that require periodic inspection, maintenance, or component replacement. Typical installations include commercial drain and waste systems, industrial process lines, and mechanical room piping where cast iron is the specified material. The black coating provides corrosion resistance appropriate for above-ground and exposed indoor piping applications.

Key Features

• Concentric reducer design maintains pipe centerline alignment for horizontal piping runs
• Flanged connection allows bolted assembly and easy field disassembly for maintenance
• Black cast iron construction provides durability and mass for demanding commercial and industrial service
• Black coating applied for corrosion resistance on exposed or above-ground installations
• Domestically produced fitting
• Weighs 31.10 pounds, consistent with heavy-duty cast iron flange construction

Compatibility

Designed as an OEM-style flanged concentric reducer for 4-inch to 3-inch cast iron piping systems using standard flanged connection configurations.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and standards. Shut down and depressurize the piping system completely before removing or installing any flanged fitting. Use appropriate gaskets and fasteners rated for the service conditions, and torque flange bolts evenly in a cross pattern following the gasket and hardware manufacturer guidelines. Inspect mating flange faces for damage or debris before assembly to ensure a leak-free joint.
