Product description

Highlights at a glance

  • Our high-pressure Hammer Union Seals are engineered to provide a reliable, leak-proof connection in the most demanding oilfield flowline applications. Designed to withstand extreme mechanical stress and fluctuating pressures, these seals are critical for maintaining the integrity of union connections in temporary and permanent pipeline installations. As a specialized manufacturer, we utilize advanced elastomer technology to ensure each seal offers superior resilience, preventing hazardous leaks and ensuring operational safety during high-stakes drilling and well-servicing projects.
  • We offer a complete range of Hammer Union Seals designed to be fully compatible with industry-standard figure numbers, including Figure 602, Figure 1002, Figure 1502, and Figure 2002. Whether your application requires a standard gasket or a high-performance lip seal, our products are precision-molded to meet exact dimensional tolerances. Available in sizes ranging from 1" to 4", these seals ensure a perfect fit for various manifold systems, mud pumps, and iron pipe connections, reducing assembly time and minimizing the risk of seal failure in the field.
  • To meet the diverse challenges of the oil and gas industry, our Hammer Union Seals are available in a variety of premium materials. Nitrile (NBR) provides excellent oil and abrasion resistance for general service, while Hydrogenated Nitrile (HNBR) is optimized for high-temperature and high-pressure (HTHP) environments and sour gas (H2S) resistance. For chemical-intensive operations or extreme thermal requirements, we offer Viton (FKM) and specialty compounds that resist explosive decompression and chemical degradation, ensuring long-lasting performance in fracturing, acidizing, and cementing units.
    • Frequently asked questions

    A Hammer Union Seal is a critical heavy-duty gasket used to create a leak-proof connection between hammer union components in oil and gas pipelines. These seals are essential for maintaining pressure integrity during high-pressure fluid transfer, preventing hazardous leaks in demanding oilfield environments like drilling and well servicing.

    Our Hammer Union Seals are precision-engineered to be compatible with standard figure numbers used in the industry. We provide high-performance seals for Fig 1502, Fig 602, Fig 1002, Fig 206, Fig 2002. Each seal is designed to match the specific pressure ratings and geometry of its corresponding figure style.

    The choice of material depends on the application. Nitrile (NBR) is ideal for general oil and water service. FKM is preferred for high-temperature and chemical resistance. For sour gas (H2S) environments, HNBR (Hydrogenated Nitrile) offers superior durability and explosive decompression resistance.

    We offer a full range of sizes for hammer union connections, typically ranging from 1 inch to 4 inches. The most common sizes for high-pressure manifolds are 2", 3", and 4", all of which are kept in stock for immediate global shipping.

    We are a source factory, offering you the most competitive prices and the best service.

    Temperature limits vary by elastomer: 1. NBR: -30°F to +250°F (-34°C to +121°C) 2. FKM: -15°F to +400°F (-26°C to +204°C) 3. HNBR: -40°F to +300°F (-40°C to +149°C)

    Yes, we manufacture specialized HNBR and FKM Hammer Union Seals that are formulated for H2S service. These materials are engineered to resist the embrittlement and cracking typically caused by sour gas, ensuring a longer service life in harsh wellhead environments.
