Stable connection: The threaded connection method is adopted, the connection is tight and stable, which can effectively prevent the joint from loosening during use, ensure the tightness and stability of the system, and can withstand a certain pressure without leakage.

Excellent material: usually nickel-plated copper body material, this material has good corrosion resistance and pollution resistance, can adapt to a variety of working environments, is not easy to rust and be corroded, can ensure the normal use and long service life of the joint, but also can avoid pollution to the pneumatic system due to material problems.

Specification adaptation: The "12" in PG12 - 8 means that one end of the joint is suitable for the outer diameter of the 12mm tube, and the "8" means that the other end is suitable for the outer diameter of the 8mm tube, this variable diameter design can easily connect the different diameter of the tube, improve the versatility and adaptability of the joint, and is widely used in all kinds of pneumatic systems.

Good flowability: The flow performance is superior, and the flow rate with the same capacity as the inner diameter of the gas pipe can ensure the smooth transmission of gas in the pipeline, reduce pressure loss, and ensure the working efficiency of the pneumatic system.
