Double-End Threaded Hex Transition Fitting

The perpendicularity and coaxiality between the external thread axes at both ends and the central hexagonal locking surface are core indicators for achieving reliable sealing and stable assembly in such fluid connectors. Featuring a design with double-ended external threads and a central hexagonal flat, this component is typically used as a straight-through transition fitting, reducer connector, or blind plug in hydraulic and pneumatic piping systems. It provides reliable wrench tightening torque in confined spaces, ensuring connection stability under high-pressure or vibrating conditions.

The manufacturing process strictly controls thread profile integrity, surface finish, and tolerance consistency of key mating dimensions to prevent leakage or stress concentration caused by misalignment during assembly. For metal materials such as stainless steel, carbon steel, or brass, precision turning using CNC lathes and Swiss-type automatic lathes effectively eliminates cumulative errors from secondary clamping. For high-hardness materials or mirror-finish requirements, external cylindrical grinding can be combined for fine machining to meet stringent mechanical connection standards.

Changzhou Senboyu Electric is equipped with Tsugami Swiss-type automatic lathes, Taikan machining centers, and high-precision grinders, supporting multi-process centralized machining from bar stock to finished products. This is particularly suitable for manufacturing non-standard parts with complex thread features. Combined with inspection tools such as Keyence vision measuring systems, pneumatic gauges, and hardness testers, we strictly screen key outer diameters, pitch, and appearance details. Surface treatments such as passivation, nickel plating, or electroless nickel plating are available to enhance corrosion resistance, providing a one-stop solution from single-piece prototyping to batch delivery.
