An o-ring is positioned between raised outer walls of the ring and secured by a cutout of the valve housing. The motor includes a brush ring assembly with brush holders and torsion springs urging brushes through the brush holders. The baseplate includes a cutout capable of allowing the use of a clamp or a wrap to couple the baseplate to the motor.
