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

SHQN offers replacement hammer union seals for flowline connections used in cementing, manifold and drilling equipment. This listing covers material and color options. Match each seal to the union manufacturer, figure, nominal size and groove; the replacement seal alone does not determine the assembly pressure rating.

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

• NBR (Buna-N): Review the selected compound against the actual hydraulic fluid and temperature
• HNBR (Hydrogenated Nitrile): Confirm compound-specific temperature, fluid and pressure-service suitability
• FKM: Review chemical and gas exposure for the specific compound; the FKM name alone does not establish sour-service qualification
• Anti-Extrusion Rings: Brass or stainless steel backup constructions require matching the equipment drawing and seal profile

• High Hardness & Tear Strength: Specify compound hardness and separate mechanical-property requirements for the selected seal
• Precision Fit: Confirm manufacturer, figure, size and groove dimensions before substituting a replacement seal
• Color-Coded Identification: Custom colors (Red, Blue, Green, Yellow) can be agreed for identification; color does not establish material or pressure suitability
• Longer Service Life: Service life depends on compound, fluid, assembly condition and operating cycles; inspect seals during planned maintenance

Custom Color and Backup Construction for Repeat Orders

For repeat purchases, quote the approved part reference and color convention together. Provide photographs of both faces and the side profile, including the backup ring. Confirm whether the support is separate, bonded or retained, and check the new seal against the groove drawing. A matching color or nominal size does not establish interchangeability. Include fluid, gas, temperature and cycling requirements when requesting a material change.

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

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.
