8" Fig 100 Threaded Hammer Union – Low-Pressure Flowline Fitting

The 8" Figure 100 Threaded Hammer Union is a colossal, general-purpose flow control component engineered for reliable, extreme-volume, low-pressure fluid routing across massive upstream, midstream, and industrial applications. Rated for a 1,000 PSI Cold Working Pressure (CWP), this economical yet highly robust hammer union provides a fast-makeup, secure connection for enormous 8-inch piping systems. It is exceptionally effective for the largest rig utility lines, extreme-capacity bulk water transfer, immense air systems, and large-scale low-pressure manifold configurations.

Manufactured from high-strength industrial-grade forged steel, the Figure 100 union utilizes a precision-machined metal-to-metal seating surface between the male and female subs. This streamlined, elastomer-free design ensures dependable pressure containment, significantly simplifying field maintenance and extending the operational lifespan of the fitting in standard utility environments. The heavy-duty wing nut features robust lug nuts that allow for rapid assembly and dismantling using a heavy hammer in the field, critically reducing rig-up times for massive temporary flowlines.

Equipped with precision-cut female threaded ends (Line Pipe), this colossal 8-inch union allows for secure, vibration-resistant integration onto standard ultra-large-bore threaded pipework. Serving as a foundational element in low-pressure fluid management, the 8" Fig 100 Hammer Union delivers extreme flow capacity, structural resilience, and rapid deployment capabilities for the largest everyday field and utility operations.

Features & Benefits

• 1,000 PSI Pressure Rating: Engineered to safely manage continuous fluid transfer in standard low-pressure systems with a 1,000 PSI Cold Working Pressure (CWP) rating.

• Extreme Flow Capacity: The colossal 8-inch bore accommodates immense fluid volumes, minimizing flow restrictions in the largest suction, transfer, and utility networks.

• Metal-to-Metal Sealing: Features a precision-machined conical and spherical seating design that provides a tight, reliable seal without the need for secondary elastomer rings, lowering maintenance needs.

• Rugged Construction: Built from industrial-grade forged steel to withstand general mechanical field handling, harsh weather conditions, and continuous line vibration.

• Threaded Connections: Precision-machined threaded ends ensure a secure, straightforward, and vibration-resistant connection to standard 8-inch threaded line pipe.

• Economical & Durable: Provides a cost-effective yet highly resilient connection for non-critical, extreme-volume utility and water lines by eliminating perishable elastomeric seals.
