Unitary, self-regulating fluid dispensing cap for a dental unit water line treatment system having both a regulator valve and a relief valve located therein, and threads to receive a fluid bottle. The cap receives unregulated high pressure air of 50-80 psi and controls and reduces the pressure to about 30-35 psi with the adjustable regulator valve. The relief valve prevents the fluid bottle from bursting if over pressure of above about 35 psi, or other selected value, builds up in the bottle.
