A malleable iron threaded coupling is a pipe fitting designed to connect two pipes of the same nominal size in a threaded piping system. Featuring female threads on both ends, it ensures a secure, aligned, and leak-tight connection. Manufactured from high-quality malleable iron and produced to international standards, threaded couplings are widely used in water supply, fire protection, gas, HVAC, and general industrial piping systems for reliable and durable pipe connections.

A malleable iron threaded coupling is a pipe fitting used to connect two pipes of the same nominal diameter in a threaded piping system. Designed with female threads on both ends, the coupling provides a secure and aligned joint, ensuring continuity of the pipeline. It is widely applied in water supply, fire protection, gas, HVAC, and general industrial piping systems.
High-strength malleable iron material: Offers excellent toughness, durability, and resistance to mechanical stress
Double female threaded design: Ensures precise pipe alignment and strong, leak-tight connections
Standardized threads: Manufactured in accordance with international thread standards for full interchangeability
Compact structure: Allows installation in confined spaces without compromising performance
Corrosion-resistant surface finish: Available in black or galvanized finish to suit different application environments
Threaded couplings are primarily used to join two straight pipes of the same size, extending pipe length or repairing existing pipelines. The threaded connection enables easy installation, disassembly, and maintenance, making couplings a practical solution for both permanent and temporary piping systems.
Typical applications include:
Water distribution and plumbing systems
Fire sprinkler and fire fighting pipelines
Gas and compressed air systems
HVAC installations
Industrial fluid and utility piping
