Description
This pneumatic push-to-connect fitting joins an air tube to a threaded port, and it comes in 4, 6 and 8 mm sizes. Business buyers can order it in bulk through GoodsAxis, which works with vetted manufacturers in China.

How a pneumatic push-to-connect fitting works
In general, a push-in fitting needs no tools to fit a tube. You push the air tube straight into the collar end, and an internal grip holds it in place. To release the tube, you press the collar and pull. Meanwhile, the threaded end screws into a port on a valve, cylinder or manifold.
This model is the straight type, which the product name calls PC straight threaded. The listing gives the connection as an external thread. As a result, the thread screws into a port that has an internal thread.

Details to confirm for this fitting
The size line reads 4/6/8 mm, so the listing names three sizes. In general, the fitting size has to match the outer diameter of your air tube. Therefore, check your tube size first. Also confirm the thread size and standard, because the listing states an external thread but gives neither.
Finally, check the material. The listing gives plastic, although the photo shows a gold-colored body. So confirm the body material and finish if your system needs a specific one.
