Fig 602, Fig 1002, Fig 1502 hammer Union API 6A Standard

Product Overview

The Fig 602 / Fig 1002 / Fig 1502 Hammer Union is designed in accordance with API 6A standards to provide a fast, reliable, and pressure-tight connection for high-pressure fluid transfer lines. Manufactured from forged alloy steel and heat-treated for maximum strength, these hammer unions ensure excellent performance in harsh drilling and production environments. They are widely used in mud, cementing, fracturing, and testing manifolds, offering quick assembly, tight sealing, and superior resistance to vibration and corrosion.
