What is the primary function of a spray gun's fluid tip?

The primary function of a spray gun's fluid tip is to meter the flow of material from the gun. The fluid tip controls the amount of paint or coating material that is dispensed as the trigger is pulled. This allows the painter to achieve the desired thickness and consistency of the applied material, which is crucial for a smooth and even finish.

A well-sized fluid tip helps ensure that the material is atomized properly as it exits the gun, contributing to an optimal spray pattern and allowing for better control over the application process. This precision is important in professional painting and refinishing work, where the quality of the finish can significantly impact the overall appearance and durability of the surface.

While temperature control, air pressure adjustment, and nozzle size play roles in the performance and outcome of spraying, they do not represent the fundamental purpose of the fluid tip itself. The fluid tip specifically focuses on regulating the material flow, making it essential for effective paint application.
