Hello Vincent;
Can you tell me how much bar air pressing did you use wtih it? I mean air pressure. 5 bar? 20 bar?
Also can you say something about tightness I mean can air escape?

I normally use 2-3 bar. My cylinders start moving at around 0.2 bar.
Well printed cylinders (no underextrusion, good straight walls etc) have only very minimal air leakage. Nothing to worry about because the air consumption during normal operation of the cylinder is much, much higher. You can always do post-processing (varnish etc) to reduce leakages further, but I don't care about that.

Thank you for your answers. We are thinking about use 3d print for air connector for some pneumatic complex stuffs. We need minimum 5 bars.

You are right, I was thinking to use varnish or some composite resines before using.

thank you

5 bar should be no problem for well-designed 3d printed parts. Also used in this video: https://www.youtube.com/watch?v=BBG-8ZSOmdY
