2" Fig 1502 Male (Wing) x 2-7/8" EUE Swage | High-Pressure Tubing Crossover Adapter

The 2" Fig 1502 Male (Wing) x 2-7/8" EUE Swage is an ultra-rugged, precision-machined crossover adapter designed to provide a highly secure, high-pressure transition directly from heavy-duty surface flowlines to larger downhole tubing strings. This specialized fitting features a 2-inch Figure 1502 Male connection (complete with the integral male sub and heavy-duty hammer wing nut) on one side, and a standard 2-7/8" External Upset End (EUE) 8-Round tubing thread on the opposite side.

Manufactured from a solid block of high-strength, heat-treated forged alloy steel, this integral swage is built to withstand the punishing mechanical stresses, massive fluid volumes, and intense vibrations inherent in large-scale well intervention and frac flowback operations. Because it is equipped with the complete male wing nut assembly, field crews can rapidly hammer this adapter directly onto any standard 2" 1502 female connection, instantly stepping the high-pressure flowline down to standard 2-7/8" EUE wellhead or production tubing.

By utilizing a seamless, integral forged design rather than a welded construction, this adapter completely eliminates structural weak points. This ensures maximum blowout resistance, mechanical integrity, and a leak-proof seal during high-capacity fluid transfer, extreme-volume well testing, and heavy-duty cementing procedures.

Features & Benefits

• Integral Forged Construction: Machined from premium, solid alloy steel forgings, eliminating weld-seam vulnerabilities and maximizing fatigue resistance under extreme pressure surges.

• Complete Male Connection: Equipped with the integral male sub and heavy-duty 1502 wing nut, allowing for rapid, hammer-up installation directly onto existing 1502 female unions without needing additional loose nuts.

• Direct Tubing Tie-In: Safely and efficiently transitions from massive 15,000 PSI surface frac iron to larger 2-7/8" EUE well tubing, streamlining rig-up and rig-down times for high-volume operations.

• High-Pressure Durability: The 2" Fig 1502 male end is engineered for 15,000 PSI Cold Working Pressure (CWP). (Note: Overall system working pressure must be regulated to the maximum safe rating of the specific 2-7/8" EUE tubing being utilized).

• Precision Machined Threads: The 8-Round EUE tubing threads are cut to exacting API tolerances to ensure galling resistance and a perfect, leak-free downhole connection.

Specifications & Technical Details

Applications

This 2" Male x 2-7/8" EUE Crossover Swage is an indispensable fitting for bridging the gap between heavy surface equipment and high-capacity downhole tubulars. It is heavily utilized in large-volume well testing operations, frac flowback tie-ins, cementing procedures, acidizing operations, and rapidly connecting high-capacity choke manifolds or temporary flowlines directly to the wellhead tubing.

Quality Assurance

Every tubing crossover swage is subjected to strict quality control protocols. The alloy steel forgings undergo ultrasonic flaw detection to verify internal structural density. Additionally, the EUE 8-Round threads are meticulously inspected using calibrated API thread gauges. The hammer nuts are individually tested for structural integrity and impact resistance to guarantee flawless field performance.
