High Pressure Resistance Hammer Union Seal with Customizable Colors and Multiple Material Options

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)

• High Hardness & Tear Strength: Compounds formulated with 80-95 Shore A hardness to withstand mechanical stresses of "hammering" and high-velocity fluid flow
• Precision Fit: Manufactured to strict industry standards (compatible with Weco®, FMC®, and other major brands), ensuring perfect fit and quick installation
• Color-Coded Identification: Custom colors (Red, Blue, Green, Yellow) to help operators quickly identify material types in the field, preventing costly errors
• Longer Service Life: Enhanced abrasion resistance significantly reduces replacement frequency and operational downtime

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

Quality: We strictly follow ISO9001 quality management systems.

Our products are trusted by clients in over 100 countries, including major markets in the Americas, Europe, and the Middle East. Shanghai Qinuo is ready to be your reliable partner.

We are a manufacturer integrating R&D, production, and sales. While our headquarters is in the Shanghai Free Trade Zone, we have a wholly-owned factory, "Nantong Ruowei Seal Technology Co., Ltd", located in Nantong City. We welcome you to visit our facilities.

We operate more than 30 rubber vulcanizing machines and related equipment. Our monthly rubber processing capability exceeds 40 tons (approx. 80,000 lbs), and we are continuously expanding our capacity to meet growing global demand.

Our factory is located in Nantong City, which is only a one-hour drive from Shanghai Pudong Airport and the Shanghai Sea Port. This strategic location ensures rapid logistics and quick delivery for our international clients.

Yes, we successfully market our products under two proprietary brands: "Royal Way" and "SHQN". These brands are recognized for quality in over 100 countries worldwide.

Absolutely. As a high-tech enterprise, we specialize in OEM and ODM services. Our R&D team can design and produce molds based on your 2D/3D drawings or samples. We currently produce more than 20 kinds of rubber rings and complex molded parts.

We process a wide range of rubber materials to suit different industrial needs, including NBR, EPDM, Silicone, FKM (Viton), CR (Neoprene), and NR. If you are unsure which material fits your application, our engineers can provide professional recommendations.

We strictly adhere to the ISO9001 quality management system. From raw material procurement to vulcanization and final inspection, every step is rigorously monitored to ensure "Quality for Survival."

Yes, we can provide samples. For stock items: Free samples are available (freight collect). For custom items: We will produce samples for approval after the mold is created. The mold cost may be refundable depending on the order quantity.

Samples/Mold creation: Typically 7-15 days, depending on complexity. Mass production: Usually 15-25 days after sample approval. Thanks to our proximity to the Shanghai port, we can minimize shipping delays.

Our MOQ is flexible depending on the product size and manufacturing process. For standard rubber rings, the MOQ might be higher, while for large or complex custom parts, we can accept smaller trial orders. Please contact our sales team for a specific quote.
