Product Overview:
The plug - in straight - through air pipe connector is mainly used for the quick connection of gas pipelines, and is also called a quick - insert air pipe connector. It is made of stainless steel for quick connection in pipelines. Generally, one end is an external thread connector, and the other end is crimp - connected to a plastic hose. However, it can also be a three - end quick - insert connector or a quick - insert elbow connector. It is widely used in electric power, electromechanical engineering, chemical machinery, pneumatic air source pipelines, and hydraulic pipelines.

Thread Description:
01 = 1 point = G1/8 pipe thread (the outer diameter of the thread is approximately 9.5MM)
02 = 2 points = G1/4 pipe thread (the outer diameter of the thread is approximately 12.7MM)
03 = 3 points = G3/8 pipe thread (the outer diameter of the thread is approximately 16.7MM)
04 = 4 points = G1/2 pipe thread (the outer diameter of the thread is approximately 21MM)
06 = 6 points = G3/4 pipe thread (the outer diameter of the thread is approximately 26MM)
