ASC Malleable Iron Union, Brass Seat for Fire Systems

The ASC Malleable Iron Union with Brass Seat is an engineered pipe connector designed to join sections of piping in fire protection, residential plumbing, and light commercial heating systems. Installed within wet pipe fire sprinklers and water supply lines, this threaded union allows you to quickly disconnect piping runs for system maintenance, inspections, and repairs without cutting or damaging the surrounding pipe.

This component complies with ASME B16.3 and ASME B16.39 standards for malleable iron pipe unions. It satisfies critical life safety installation requirements as a UL Listed and FM Approved fitting suitable for high-pressure fire suppression and sprinkler configurations.

Key Features & Construction

• Malleable Iron Build: Constructed from high-strength malleable iron that provides superior ductility and resilience against high-pressure fluctuations in gas, water, and steam applications.
• Brass-to-Iron Seat: Features a precision-machined brass seat that forms a rigid, leak-resistant seal while enabling smooth disconnection of piping joints.
• Corrosion Resistance: Available with protective galvanized or black coatings that create a barrier against rust and environmental wear in demanding mechanical rooms or wet pipe networks.
• Threaded Union Design: Utilizes precision-cut threads that facilitate rapid assembly and disassembly to minimize equipment downtime during facility upgrades.

Technical Specifications & Compliance Table

Verify all local Authority Having Jurisdiction (AHJ) guidelines and system design parameters prior to assembly. Always consult the manufacturer's technical documentation to ensure compatibility with your specific working pressure and fluid requirements.
