SHQN's Hammer Union Seals are designed to provide reliable, leak-proof connections in demanding high-pressure flow line applications. Specifically engineered for the oil and gas industry, our seals are used in cement trucks, manifold systems, and drilling rigs. Whether dealing with abrasive fluids, high-pressure fracturing, or extreme temperatures, our seals ensure structural integrity for hammer union connections (Fig 100 to Fig 2202).

To meet different wellhead conditions, we offer various high-performance materials:

• NBR (Buna-N): Excellent oil resistance, ideal for standard hydraulic services
• HNBR (Hydrogenated Nitrile): Superior heat resistance and chemical stability; perfect for high-temperature and high-pressure (HTHP) environments
• FKM: Outstanding resistance to aggressive chemicals, H2S, and high temperatures
• Anti-Extrusion Rings: Available with Brass or Stainless Steel backup rings to prevent seal extrusion under extreme pressure (essential for Fig 1502 and 2202)

• Fig 206: 1" 1.5" 2" 3" 4" 6" 8"
• Fig 602/1502: 1" 1.5" 2" 3" 4" 7"
• Fig 607: 2"
• Fig 1002: 5"
• Fig 1003: 4"
• Customized: oversized models 

• Fracturing (Frac) stacks and manifolds
• Acidizing and cementing lines
• Mud pumps and suction lines
• Well testing and flowback equipment
