The sink sprayer attachment apparatus is for attachment to an existing hose such as that typically associated with a sink. The spray head fitting is installed on the spray head. Spray head fittings are provided with male and female threads and other forms of attachment to spray heads. The apparatus negates the need for total hose replacement, a feature that saves considerable expense and installation time and effort. The apparatus importantly provides for component disposability, and therefore ideally employs plasticized components and other inexpensive materials.
