押 centers on applying force to move, hold, or mark something: pushing, pressing, or shoving an object; stopping or subduing movement; attaching a seal or weight; and doing something in spite of resistance.
押 combines 扌 (hand) with 甲, which likely contributes the sound and may suggest pressing down like a shell or armor. The exact historical role of 甲 is uncertain.
A hand 扌 pressing down on a hard shell 甲: imagine pushing a stamp onto a document, subduing it with force.
For オウ, picture an 'O' ring being pushed onto a pipe: 'O' -> オウ, and your hand presses it firmly into place.
