1" Fig 1002 Threaded Hammer Union – Oil & Gas Flowline Fitting

The 1" Figure 1002 Threaded Hammer Union is a heavy-duty, high-pressure flow control component expertly engineered for secure and rapid fluid routing in demanding upstream oil and gas operations. Rated for an impressive 10,000 PSI Cold Working Pressure (10M CWP), this compact yet incredibly resilient hammer union provides a reliable, fast-makeup connection for 1-inch piping systems, making it an essential asset for cementing, acidizing, high-pressure well testing, and choke-and-kill line configurations.

Manufactured from premium high-strength forged alloy steel, the Figure 1002 union is built to endure the extreme internal stresses, mechanical impacts, and abrasive environments typical of severe oilfield service. It features a specialized, replaceable lip-type elastomeric seal ring that fits securely into the female sub. This primary seal protects the secondary metal-to-metal seating surface from abrasive fluids and corrosive agents, ensuring absolute bubble-tight pressure containment and significantly extending the lifespan of the union.

Equipped with precision-cut threaded ends (NPT / Line Pipe), this 1-inch union allows for secure and straightforward integration onto standard threaded pipework. The robust wing nut design enables fast, tool-free assembly and dismantling in the field, critically reducing rig-up times while maximizing structural safety in high-pressure networks.

Features & Benefits

• 10,000 PSI Pressure Rating (10M): Engineered to safely manage extreme high-pressure fluid systems with a 10,000 PSI Cold Working Pressure 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 pressure containment.

• Precision NPT Threads: Features standard threaded ends for quick, 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 severe mechanical impacts and high-velocity fluids.

• Rapid Makeup Design: The heavy-duty wing nut allows for quick, ultra-secure connections and disconnections in the field, optimizing operational efficiency.
