AlienFrac Fig 602 hammer unions are 6,000 PSI NSCWP wing unions for manifold, line connection, truck-mounted and mud service. The resilient nitrile-butadiene lip-type seal provides primary sealing, helps protect the secondary metal-to-metal seat, and reduces flow turbulence. Available with threaded or butt-weld ends, black nut/orange subs, and full inspection support for oilfield flowline systems.
Fig 602 is a compact medium/high-pressure hammer union designed for quick make-up and break-out in temporary or semi-permanent flowline connections. It is commonly selected when a 6,000 PSI connection is required but size and weight must remain manageable.
For figure 602, 6000PSI NSCWP, test pressure at 9000PSI with black nut and orange parts.

Typical applications include manifold and line connections, truck-mounted pumping systems, mud delivery and circulating lines, well-service flowlines, pressure-test loops, and verified Weco-style replacement systems.
Use forged steel components with machined threads and sealing faces. For each order, confirm material grade, heat number traceability, seal material, inspection report, hydrostatic test requirement and any sour-service or low-temperature requirement.
