1" Fig 602 Threaded Hammer Union – Oil & Gas Flowline Fitting

The 1" Figure 602 Threaded Hammer Union is a compact, heavy-duty flow control component engineered for dependable fluid routing in medium-to-high pressure upstream and midstream operations. Rated for a 6,000 PSI Cold Working Pressure (CWP), this resilient hammer union provides a highly secure, fast-makeup connection for 1-inch piping systems, making it an ideal choice for well servicing operations, mud lines, cementing applications, and standard manifold configurations.

Manufactured from premium high-strength forged steel, the Figure 602 union is built to withstand the rigorous mechanical demands of continuous field service. Its hallmark feature is the specialized, replaceable lip-type elastomeric seal ring embedded within the female sub. This primary elastomeric barrier effectively protects the secondary metal-to-metal seating surfaces from abrasive fluids and corrosive elements, ensuring bubble-tight pressure containment and significantly extending the lifespan of the union components.

Equipped with precision-cut female threaded ends (NPT / Line Pipe), this 1-inch union integrates seamlessly onto standard threaded pipework, creating a robust connection point that effectively resists vibration and pressure surges. The heavy-duty wing nut allows for rapid, tool-free assembly and dismantling in the field, optimizing rig-up times while maximizing structural safety across medium-pressure fluid networks.

Features & Benefits

• 6,000 PSI Pressure Rating: Engineered to safely manage medium-to-high pressure fluid systems with a reliable 6,000 PSI Cold Working Pressure (CWP) rating.

• Replaceable Lip-Type Seal: Features a resilient elastomeric seal ring that provides a dependable primary barrier, minimizing turbulence and protecting metal seating surfaces from abrasion.

• Dual Sealing Mechanism: Combines the primary elastomer seal with a precision-machined secondary metal-to-metal seat for ultimate, leak-free pressure containment.

• Precision NPT Threads: Features standard threaded ends for quick, secure, and vibration-resistant makeup onto 1-inch threaded line pipe.

• Forged Steel Construction: Built from heavy-duty forged steel to deliver exceptional durability and resistance against mechanical impacts and rough field handling.

• Rapid Makeup Design: The robust wing nut enables quick, ultra-secure connections and disconnections in the field, drastically reducing operational downtime.

Specifications & Technical Details

Applications

This compact 1" Figure 602 threaded hammer union is essential for medium-to-high pressure flowline networks requiring reliable, leak-free containment. Typical applications include well servicing lines, standard cementing and pump discharge operations, mud mixing configurations, truck-mounted pumping manifolds, and general oilfield fluid routing where 6,000 PSI pressure containment and fast rig-up times are critical.

Quality Assurance

Each hammer union assembly undergoes strict quality control protocols, including precision dimensional verification, exact thread gauging, and material traceability (MTRs), ensuring complete structural integrity, safe pressure containment, and reliable compatibility with industry-standard Figure 602 components.
