Hex Body Plug With Double External Threads and Central Through Hole

This cylindrical component features double-ended external threads and a central through hole, with an integrated hexagonal flat on the side for easy installation and tightening. It is commonly used as a transition fitting or blind plug in hydraulic and pneumatic piping systems. This design ensures effective tightening with a wrench even in confined spaces, while maintaining the flow or sealing of fluid channels.

The manufacturing process strictly controls the coaxiality of the threads at both ends and the perpendicularity of the hexagonal face to the axis to prevent misalignment and subsequent seal failure during assembly. Changzhou Senboyu utilizes CNC lathes and sliding headstock automatic lathes for precision turning, stably ensuring the integrity of thread profiles and meeting tight tolerance requirements for key mating dimensions, thereby satisfying stringent mechanical connection standards.

The part surface exhibits a natural metallic luster. Surface treatments such as passivation, nickel plating, or electroless nickel plating can be applied based on actual operating conditions to enhance corrosion resistance. The factory is equipped with inspection devices such as 2D video measuring systems and hardness testers, supporting strict inspection of bore diameter, wall thickness, and surface defects according to drawings to ensure consistency in batch deliveries.
