Asc Engineered Solutions 306059809 Cast Iron Reducer 5x4

Product Description

The ASC Engineered Solutions 306059809 is a flanged, 125-class concentric reducer manufactured from black cast iron. It reduces piping from 5 inches to 4 inches and is designed for use in industrial and commercial piping systems where flanged connections and durable iron construction are required. The concentric reducer maintains a centered pipe axis, making it well-suited for straight-run installations. This fitting is domestically manufactured and carries a black coating for corrosion inhibition. Plumbers, pipefitters, and mechanical contractors install this type of reducer in process, HVAC hydronic, and fire protection piping assemblies.

This reducer is appropriate for 125-class flanged piping systems in both commercial and industrial applications. The flanged connection style accommodates systems that require accessible, bolted joints rather than threaded or welded ends. Its concentric geometry suits horizontal and vertical installations where flow alignment is a priority. At 46.80 pounds, this is a heavy-duty fitting suited for permanent installations where long service life and pressure integrity are required.

Key Features

• Flanged 125-class connection for bolted piping assemblies
• Concentric reducer design maintains centered pipe axis through the transition
• Cast iron construction provides durability in demanding commercial and industrial service
• Black coating applied for corrosion inhibition
• Domestically manufactured
• 5 inch inlet to 4 inch outlet sizing for standard reducing applications

Compatibility

Designed as an OEM-style flanged fitting for 125-class cast iron piping systems requiring a concentric 5-inch to 4-inch reducer connection.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes. Depressurize and drain the system before removing or installing any flanged fitting. Use appropriate flange gaskets and hardware torqued evenly in a cross pattern to ensure a leak-free seal. Verify that the existing flange class and bolt pattern match this 125-class fitting before installation.
