2" Fig 206 Threaded Hammer Union – Low-Pressure Flowline Fitting

The 2" Figure 206 Threaded Hammer Union is a highly reliable flow control component engineered for general-purpose, low-pressure fluid routing across upstream, midstream, and industrial applications. Rated for a 2,000 PSI Cold Working Pressure (CWP), this robust hammer union provides a fast-makeup, highly secure connection for standard 2-inch piping systems. Building upon the standard Figure 200 design, the Figure 206 union is distinctly upgraded with a secondary elastomeric O-ring embedded directly into the spherical seating surface of the male sub.

Manufactured from high-strength industrial-grade forged steel, the Figure 206 union utilizes a dual-sealing mechanism. The primary metal-to-metal conical and spherical seating surface is reinforced by the resilient O-ring, which effectively fills microscopic imperfections and compensates for minor pipe misalignments. This makes the Figure 206 particularly effective for corrosive fluids, mildly abrasive mud lines, and water transfer configurations where achieving a perfect metal-to-metal seal is challenging.

Equipped with precision-cut female threaded ends (NPT / Line Pipe), this 2-inch union allows for secure, vibration-resistant integration onto standard threaded pipework. The heavy-duty wing nut allows for rapid, tool-free assembly and dismantling in the field, critically reducing rig-up times while delivering enhanced leak prevention for everyday field and utility operations.

Features & Benefits

• 2,000 PSI Pressure Rating: Engineered to safely manage continuous fluid transfer in standard low-pressure systems with a reliable 2,000 PSI Cold Working Pressure (CWP) rating.

• Secondary O-Ring Seal: Features an elastomeric O-ring embedded in the male sub, providing an enhanced secondary seal that significantly improves leak-free performance, especially in less-than-ideal alignment conditions.

• Dual Sealing Mechanism: Combines traditional metal-to-metal seating with a resilient O-ring to ensure dependable pressure containment against corrosive or mildly abrasive fluids.

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

• Threaded Connections: Precision-machined NPT threaded ends ensure a secure, straightforward, and vibration-resistant connection to standard 2-inch threaded line pipe.

• Rapid Makeup Design: The robust wing nut allows for quick, ultra-secure connections and disconnections in the field, optimizing operational efficiency and saving critical rig-up time.

Specifications & Technical Details

Applications

This 2" Figure 206 threaded hammer union is an essential component for reliable, low-pressure fluid systems where an extra layer of seal integrity is desired. Typical applications include heavy-duty mud lines, standard water and chemical transfer networks, general rig utility lines, pump suction routing, bulk storage tank tie-ins, and general industrial fluid transfer where rapid rig-up and dependable 2,000 PSI containment are required.

Quality Assurance

Each hammer union assembly undergoes rigorous quality control protocols, including precision dimensional verification, exact thread gauging, O-ring groove inspection, and full material traceability (MTRs), ensuring complete structural integrity, safe pressure containment, and reliable field performance.
