Sealed piston apparatus and related systems for use with vehicle torque converters are disclosed. A disclosed vehicle torque converter includes a housing and a clutch including a piston in the housing. The piston has a first side partially defining a first chamber and a second side, opposite the first side, partially defining a second chamber. The vehicle torque converter also includes a first seal operatively coupled to the piston and a second seal operatively coupled to the piston. The vehicle torque converter also includes an orifice positioned on the piston radially inward relative to a clutch pack of the clutch. The orifice is configured to provide a flow of a fluid between the first and second chambers during a lockup on operation of the vehicle torque converter to lubricate the clutch. The first seal is a one-way seal.
