The Grex CP05-SS Airbrush Side Cup Set is a side-feed airbrush cup accessory set for painters who want quicker color changes and easier cleanup. This is an airbrush cup set designed for side-feed airbrush painting and color management. Model Number: CP05-SS. If you already use a Grex side-feed airbrush, this set gives you multiple ready-to-go cups instead of tying up your workflow with constant rinsing and refilling.

What makes this set useful is how it handles real bench work. Each cup includes a plug so paint can be stored in the cup between passes or between colors. That means you can preload color, cap it, and come back to it without dumping material back into a bottle. The cups can also convert to a siphon bottle setup to hold more solvent, which is a practical way to flush leftover color when switching paints.

Grex builds these cups from solid aluminum with a one-piece machined design. That matters because cleanup is easier when there are fewer seams, crevices, or thin formed parts to trap paint. The anodized finish also helps with durability and day-to-day maintenance, especially if you are cleaning often with reducer or solvent between sessions.

The large flat bottom is not just a small design note. It lets each cup sit firmly on the bench instead of rolling around or tipping as you work. For anyone mixing small paint batches, doing touch-up work, or setting up several colors at once, that stable base is a genuine convenience. Precision-fit lids help keep paint in the cup, and the included plugs add another layer of control when you need to pause without making a mess.

On compatibility, this airbrush accessory set is made for all Grex side-feed airbrushes and is also listed as compatible with most Iwata side-feed airbrushes. The package also calls out use with Grex Genesis.XSi, Genesis.XS, Genesis.XT, and Tritium.TS models. If you are already in the Grex platform, this is the cleanest use case. If you run a side-feed Iwata, check your connection style, but this set is clearly intended to cover a wide range of side-feed setups.

This set makes the most sense for model painters, illustrators, custom finish users, hobbyists, and detail painters who regularly change colors and need a cleaner, more organized process. If you only ever spray one color at a time, it is a convenience item. If you switch colors constantly, it becomes a real workflow upgrade.
