150lb Class 1/4" NPSC Galv. Mall. Iron Ground Joint Pipe Union

The 150lb Class 1/4" NPSC Galvanized Mall. Iron Ground Joint Pipe Union (66641) is a specialized connector used in piping systems to facilitate the separation and connection of pipes. Ground joint unions are typically employed in applications where frequent disassembly is required for maintenance or inspection. Manufactured from galvanized malleable iron, this product is designed to resist corrosion and withstand the rigors of both residential and industrial environments. The 1/4" nominal pipe size ensures compatibility with various piping systems, while the NPSC (National Pipe Straight Coupling) threading provides a secure and leak-proof connection. Ground joint unions are particularly common in plumbing, HVAC, and irrigation systems, allowing for easy reconfiguration of piping layouts without the need for extensive rework. Their robust construction makes them capable of handling pressures up to 150 pounds per square inch (psi), making them suitable for high-pressure applications. Unique features of this product include its ground joint design, which creates a flat surface for better sealing, and its galvanized finish, providing enhanced durability against environmental factors. This makes the 150lb Class NPSC union an essential component for professionals in plumbing and piping industries.
