3 Inch NBR HNBR FKM Hammer Union Seal Ring, China OEM Hammer Union Seal for Frac Flowlines

When a fracturing spread moves high-volume fluid through large-bore lines, every union connection needs a seal that fits the equipment configuration and supports an efficient maintenance program. This 3 inch FIG 1502 hammer union seal is developed for pressure-pumping flowlines, frac manifolds, cementing lines and well-testing assemblies. Royal Way brings rubber-compound processing and molded-seal manufacturing together, helping purchasing and service teams source a consistent replacement component for their equipment program.

Product Highlights

• Large-bore pressure-pumping service: a dedicated 3 inch seal option for FIG 1502 hammer union flowline and manifold connections.
• Elastomer choices for project conditions: NBR, HNBR and FKM compounds can be selected around the fluid, temperature, wear exposure and maintenance plan.
• Connection-focused configuration: seal profile and backup-ring arrangement can be coordinated with the equipment drawing and specified union design.
• Direct factory support: compound mixing, rubber molding, vulcanization, finishing and inspection are coordinated through one manufacturing team.

Technical Specifications

Compound Selection for Oilfield Flowlines

NBR is a practical choice for many oil-based service environments and routine replacement programs. HNBR supports demanding oilfield applications where enhanced mechanical performance is specified. FKM is selected for projects requiring resistance to particular oils, fuels or chemical media. We work from your fluid description, service temperature, wear conditions and equipment specification to align the compound with the intended application.

For assemblies using a backup ring, brass and stainless-steel options can be matched to the connection drawing. Share the union manufacturer, figure, nominal size and seal profile to help our team identify the right configuration and prepare a clear product specification for purchasing and maintenance.

From Compound Mixing to Finished Seal

Royal Way manufactures rubber sealing products at its Haimen facility in Jiangsu, China. The production team coordinates rubber-compound preparation, mold setup, molding and vulcanization, edge finishing and final inspection. This integrated workflow gives oilfield buyers a direct route from application discussion to a made-to-specification seal, with production priorities organized around the approved drawing, material callout and order requirements.

Our ISO 9001:2015 quality management system supports disciplined manufacturing and inspection for rubber seals. For projects built around applicable API technical requirements, Royal Way coordinates the specified edition, product drawing, compound callout and inspection documentation with the customer's equipment package, helping the purchasing and engineering teams keep product details aligned throughout sourcing.

OEM, Drawing-Based Customization and Supply Support

One seal profile can serve a specific equipment configuration, while a field program may include several sizes, materials and backup-ring arrangements. Our team can organize custom seal development from a sample, part number or technical drawing and coordinate hardness, compound, color, packaging labels and kit grouping. This makes it easier to standardize replacement inventory across a service fleet and keep repeat orders tied to the same approved product details.

For a quick quotation, send the nominal size, FIG connection, equipment or union brand, seal drawing or sample, compound preference, required quantity and packing method. Our product team can help prepare a clear configuration for pressure-pumping and flowline service.
