Royal Way's 3-inch FIG 1502 hammer union seal supports oilfield flowline maintenance, pressure-pumping equipment and project spare-part programs. This product page focuses on a high-interest size and connection family, with drawing-led options for seal geometry, elastomer compound and inspection documentation. A coordinated specification helps buyers source a seal around the actual union assembly and service brief.


The product images show union-seal profile options. Drawing-based configuration connects the product selection to the specific 3-inch FIG 1502 hardware.

Maintenance teams can build a clear spare specification around the 3-inch connection, selected seal profile and compound. Material choice can be organized around the service medium and required operating conditions, with hardness and backup-ring details included in the drawing or purchase brief. Royal Way supports custom rubber-seal configurations for customer-defined equipment requirements.
Jiangsu Ruowei's Haimen site carries out the core rubber-seal steps of compound mixing, molding, vulcanization, trimming and inspection. Its production and quality resources support drawing-based oilfield components from prepared compound to dimensional and material checks. An order-specific quality plan can set the required checks and acceptance points for each configuration.
The ISO 9001:2015 certificate scope covers production of rubber seals. When a project specifies API equipment requirements, the applicable edition, customer drawing and acceptance criteria can be reflected in the manufacturing and inspection plan, helping engineering and procurement teams keep the product specification aligned with the project.
