Durable Hammer Union Seal Designed for Ring Seals and Weco Seals Suitable for Fig206 602 607 1002 1003 and 1502 Applications

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"
