  • Functional fittings
  • Female thread/male thread
Our development and production of functional fittings with female and male threads is an important area in the industry that focuses on the connection of pipes and hoses in pneumatic systems. These fittings make it possible to connect different threads, allowing flexible integration of components in pneumatic systems.

The development of internally and externally threaded functional fittings requires careful planning and design to ensure that the fittings meet the requirements of the application. This includes factors such as the size and shape of the tubing and hoses, the type of fluid used, and the temperature and pressure to which the fittings will be subjected.

High-quality materials such as stainless steel and brass are used in the manufacture of female and male functional fittings to ensure that the fittings are durable and robust. Modern manufacturing technologies, such as CNC machining, enable high precision and quality in production.

As a manufacturer of female and male functional fittings, we specialize in providing our customers with fittings that meet the highest standards and meet their specific requirements. We offer customized solutions to ensure that the fittings can be seamlessly integrated into their systems and function optimally.
