Asc 500016811 Malleable Iron Reducing Rod Coupling 1/2x3/8

Product Description

The ASC Engineered Solutions 500016811 is a malleable iron reducing rod coupling designed to connect threaded rods of two different diameters in structural support and suspension applications. This black-finish fitting transitions from a 1/2-inch thread to a 3/8-inch thread, allowing mixed-diameter all-thread rod assemblies to be joined securely. At 0.21 pounds, it is a compact, heavy-duty fitting suited for mechanical, electrical, and plumbing suspension systems. Licensed contractors and tradespeople across multiple disciplines install this type of coupling as part of pipe hangers, equipment supports, and seismic bracing assemblies.

This reducing rod coupling is used in commercial and residential construction where threaded rod support systems require a diameter transition. Typical applications include suspended piping hangers, conduit support assemblies, mechanical equipment support frameworks, and ceiling-suspended HVAC ductwork systems. The black finish is standard for interior structural applications where uncoated malleable iron is acceptable per local specifications.

Key Features

• Reduces from 1/2-inch to 3/8-inch threaded rod in a single fitting
• Malleable iron construction for strength and impact resistance in support applications
• Black finish standard for interior structural and mechanical use
• Compact, lightweight design at 0.21 pounds for easy handling and installation
• Internally threaded on both ends for direct all-thread rod engagement

Compatibility

Designed as an OEM-style replacement and standard fitting for threaded rod suspension and support assemblies using 1/2-inch and 3/8-inch all-thread rod.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, electricians, or mechanical contractors working within applicable building codes. Shut down or de-energize any systems supported by the existing hanger assembly before modifying rod connections. Use appropriate pipe wrenches or hex tools to thread the coupling onto rod ends and ensure full thread engagement on both sides. Do not overtighten in a way that damages the internal threads of the malleable iron fitting.
