Sour Gas Resistant FKM HNBR Steel or Brass Sleeve Figure 1502 602 Hammer Union Seal for Oil Rig

What we supply:

Hammer union seals from Shanghai Qinuo are precision-engineered to provide dependable sealing performance in demanding oilfield conditions. These seals are widely used in high-pressure flowlines, choke and kill manifolds, drilling mud circulation systems, cementing operations, and fracturing equipment. Each seal is manufactured to provide a stable, fluid-tight connection that prevents leaks caused by pressure surges, corrosive media, or abrasive solids within the flow stream.

Our seals are designed with a robust lip-style profile that ensures proper seating inside the hammer union cavity, preventing accidental displacement during installation or heavy-duty operation. Materials are selected based on application needs: NBR offers excellent oil resistance, HNBR handles elevated temperatures and mechanical stress, while FKM resists harsh chemicals, H₂S sour gas, and extreme well-site environments.

We produce hammer union seals in sizes ranging from 1" to 7", compatible with Weco and FMC hammer union models including Fig 602, 1002, 1502, and 2002. For extreme high-pressure service, optional brass or stainless steel anti-extrusion rings keep the seal stable under loads exceeding 15,000 psi. Qinuo’s seals provide long-term durability, reduce equipment wear, and ensure reliable performance in critical oil and gas operations.
