In the video, a man is seen working on a piece of machinery. He is wearing a black shirt with red stripes on the sleeves and has a ring on his left hand. The man is holding a black metal tube in his hands and is pointing to a small black metal piece that is attached to the tube. The tube is resting on a metal table with several holes in it. The background shows a red toolbox and a gray metal piece on the floor. The man is talking about the small metal piece, but the audio is not available.
