Malleable Iron Flange Adapters and Grooved Flange Connectors are designed to bridge threaded or grooved piping systems with flanged pipelines.
Featuring hot-dip galvanized coatings (C5-M standard) and UL/FM certifications, these adapters ensure leak-proof connections in high-pressure fire protection, HVAC, and industrial applications.
Flange adaptors are used to connect networks composed of different materials or are specially designed for a specific material. They effectively join a flanged part to the spigot end of a pipe or tube. Available in both anchoring and non-anchoring versions, the self-anchoring (locking) products do not require concrete anchor blocks.

Optimized Selection of High-Performance Ductile Iron Materials for Precision Products to Ensure Superior Strength, Corrosion Resistance, and Construction, and Industrial Applications While Adhering to ASTM/ISO Quality Standards.
Standardized production of Malleable Iron Fittings and Grooved Pipe Fittings for diverse order volumes – from small-batch HVAC components to bulk fire protection systems – with precision threading, UL/FM certifications, and seamless integration across ANSI/DIN/BS pipe standards, ensuring rapid delivery and consistent quality for plumbing, construction, and industrial projects.
Uniform machine production utilizing CNC precision engineering and automated quality control systems ensures strict dimensional consistency (±0.1mm tolerance) across all malleable iron threaded fittings and grooved pipe couplings, eliminating size variations from 1/8″ to 24″ diameters. Advanced robotic casting and laser-calibrated threading guarantee ISO 9001-certified standardization for fire protection, HVAC, and waterworks applications, with UL/FM/ANSI-compliant outputs that streamline installation timelines by 40% while reducing material waste and project costs.
Customized malleable iron fittings and grooved pipe couplings are engineered to precise specifications – from non-standard thread patterns (NPT/BSPP/BSPT) and bespoke groove dimensions (Victaulic-style/rigid/flexible) to tailored coatings (epoxy/zinc-aluminum/PTFE) – supporting unique requirements in fire protection, oil & gas, and marine systems. Leveraging 3D-scanning prototyping and batch-specific material certifications (ASTM A197/EN 1563), we deliver OEM-ready solutions with ±0.05mm dimensional accuracy, UL/FM/CE/API 6A compliance
