Ordering by number: this is 1280582366 the number that superseded 18503, the American Pneumatic Tool dixon fitting – 3/8″ male #AM8. It makes the air or hydraulic connection to the tool. Thread and sealing-face condition here is the difference between full pressure at the tool and a slow leak nobody notices.
