An electric motor having a watertight construction, comprising:

• a motor housing, having an open end face with an axially protruding edge;
• a bearing plate having a brush plate and a circumferential groove;
• an insulated lead-insert made of an insulating material and capable of holding a plurality of electrical leads coupled to the electric motor disposed within said motor housing, said insulated leadinsert arranged between the axially protruding edge of said motor housing and said bearing plate;
• a circumferential sealing ring molded on said insulated lead-insert, said circumferential sealing ring is molded onto the brush plate of said bearing plate as a preassembled unit, the groove of said bearing plate is capable of receiving and position in said sealing ring;
• and
• a plurality of securing bars coupling said sealing ring to the brush plate of said bearing plate, such that when the axially protruding edge of said motor housing is joined to said bearing plate, said sealing ring is pressed against the axially protruding edge of said motor housing by said bearing plate forming a watertight seal.
