The Malleable Cast Iron Union is a high-performance detachable fitting engineered for seamless piping systems. Featuring dual female threaded connections, this professional-grade union consists of a precision-engineered tail (male part), a head (female part), and a securing union nut. Available with both flat and taper seat options, it ensures a leak-proof seal and provides the flexibility needed for easy maintenance and equipment replacement without dismantling the entire pipeline.
Manufactured by Pannext, a leader with over 30 years of expertise in the casting field, these unions are produced using advanced casting techniques and rigorous quality control. Whether you require a black finish for standard applications or a galvanized coating for enhanced corrosion resistance, our unions meet strict industry standards, providing unparalleled structural integrity and reliability for industrial metal pipe fitting requirements.

Frequently Asked Questions
A flat seat provides a surface-to-surface seal, while a taper seat uses a conical shape to create a wedge-like seal. The choice depends on the specific pressure requirements and the type of sealing medium used in your piping system.
Yes, especially our galvanized versions. The galvanized coating provides excellent corrosion resistance, making them ideal for outdoor installations and humid environments.
Absolutely. Our products are manufactured to meet ANSI B 16.3 dimensions and are available in both NPT (National Pipe Taper) and BSP (British Standard Pipe) threads to ensure global compatibility.
We offer a wide range of sizes starting from 1/8" all the way up to 6" to accommodate various industrial pipe diameters.
Malleable iron undergoes a heat treatment process (annealing) that makes it less brittle and more ductile than standard gray cast iron, providing better impact resistance and strength for pressurized systems.
Yes, in addition to our standard black and galvanized finishes, we can discuss specific technical requirements with our experienced production team to meet your application's needs.
