Convenient and fast connection: As a push-in fitting, no tools are required, just insert the air hose alignment joint, and the connection can be quickly realized, which greatly improves the installation efficiency and saves a lot of time and labor costs when the pneumatic system needs to be quickly assembled or repaired.

The material is excellent and durable: usually made of nickel-plated copper or high-quality engineering plastics. Nickel-plated copper material has good corrosion resistance, strength and conductivity, can adapt to a variety of complex working environments, and is not easy to rust and be corroded; Engineering plastic material is light weight, good insulation, low cost, but also has a certain strength and corrosion resistance, which can ensure the normal use and long service life of the joint under different conditions.

Specification and size adaptation: "12" generally means to adapt to the trachea with an outer diameter of 12mm, which is designed to be well matched with the trachea and pneumatic components of the corresponding diameter, with strong versatility, and can be widely used in various pneumatic systems, which can meet the connection needs of different equipment and pipelines.

Good sealing performance: The connection parts of the joint are usually sealed design, such as O-ring sealing, etc., to ensure good sealing and effectively prevent gas leakage. Even under a certain pressure fluctuation, it can maintain a stable sealing effect and ensure the normal operation of the pneumatic system.

Reasonable shape design: the overall shape is compact and lightweight, which not only saves installation space, but also facilitates the layout and installation in different equipment and systems, and will not affect the compactness and aesthetics of the overall structure due to the excessive volume of the joint. At the same time, its shape design is also conducive to the reasonable layout of pipelines and the smooth flow of airflow.
