Malleable Iron Coupling for Fire Protection | UL/FM Approved | ASC

The ASC Malleable Iron Coupling serves as a critical threaded connector designed to join piping segments securely within fire sprinkler and suppression networks. Installed in commercial, industrial, and residential wet or dry fire protection assemblies, this fitting delivers a rigid, leak-proof mechanical link that withstands high-pressure operational demands without deformation.

Engineered to comply strictly with NFPA 13 standards for fire sprinkler system installations, this component satisfies mandatory life safety codes for reliable network integration. The design carries both UL Listing and FM Approval, verifying that the fitting meets rigorous third-party safety testing parameters and real-world loss prevention criteria.

Key Features & Construction

• Malleable Iron Build: Forged from high-quality malleable iron to provide toughness, flexibility, and resistance to mechanical stress, impact, and vibration.
• Corrosion Resistance: Resists rust and environmental deterioration in high-humidity or chemical-exposure areas, protecting pipe walls and preventing sprinkler head clogs.
• Threaded Installation: Features precisely machined threads that streamline on-site assembly, creating a secure mechanical seal while reducing labor time compared to welding or flanging.
• System Versatility: Integrates seamlessly into both wet and dry fire sprinkler piping configurations across commercial, industrial, and residential environments.

Technical Specifications & Compliance Table

Contractors must verify local Authority Having Jurisdiction (AHJ) requirements and consult manufacturer technical data sheets to confirm proper sizing and pressure limits prior to installation.
