Spray gun cups hold the paint or other coating material and provide a steady flow of material to the spray gun.

Spray gun cups come in a variety of shapes and sizes to accommodate different types of paint and coatings. Some common types include gravity cups, pressure cups, and siphon cups.

The type of spray gun cup you need will depend on the type of paint or coating you are using, the size of the job, and your personal preferences.

Cleaning a spray gun cup is important to prevent clogging and ensure proper performance. The best way to clean a spray gun cup is to use a solvent that is compatible with the paint or coating you are using.
