Ever wonder what's inside a Schrader valve every time you connect a service hose? This animation cracks a Schrader valve open in full cutaway so you can see the internal components most techs never actually get to look at.

Inside the assembly, a spring-loaded pin sits sealed against pressure until something pushes it open — that’s the whole mechanism most people never think twice about. The video covers the service port, service hose connection, core depressor, hose gasket, and the valve core itself, shown moving between open and closed. Understanding what’s inside helps when you’re diagnosing a slow leak or a stuck core out in the field. Watch the full 3D breakdown to see exactly how a properly sealed connection works, start to finish, in 3D.
