When your compressor is running, the intake valve (usually a flapper type) opens on the downstroke, allowing air to be pulled into the cylinder by the piston as it recedes. The flapper valve into the tank line is pulled closed at the same time.

When the piston compresses the air, the intake valve is forced shut, and the pressure valve to the tank is forced open.

If air is bleeding out the intake valve as the compressor is running, you need to fix the valve. It likely has nothing to do with the piston seals.
