Spray gun paint cups

Start with cup capacity to fit your job duration; larger cups reduce frequent refills but add weight. Check the material, with stainless steel options favored for durability and easy cleaning, as seen in 100mm stainless steel cups in this listing. Ensure compatibility with your spray gun brand, whether Bosch, Total, or generic models, and confirm thread size and nozzle compatibility. Finally, consider the cup’s seal quality to prevent leaks during use.

Bigger capacity reduces reloading interruptions, which speeds up large jobs, but heavier cups can affect balance and control during spraying. Also, larger cups may require more careful maintenance to prevent drips and spills at the outlet. For most DIY tasks, a mid-range cup offers a practical balance of capacity, weight, and maneuverability while maintaining consistent spray patterns.

Match cups by checking the thread size, nozzle compatibility, and whether the cup’s material suits the paint type. Brands like Bosch and Total typically specify standard thread patterns that fit common units; generic cups require careful verification against your gun’s model. Always read the product descriptions for compatibility notes and choose stainless steel cups for longevity and chemical resistance.

Rinse cups immediately after use with an appropriate solvent or water, depending on the paint type. Dry cups completely to prevent corrosion, then store with lids on to avoid dust ingress. Regularly inspect gaskets and seals for wear and replace as needed. Avoid leaving solvents in cups overnight, and wipe down the exterior to reduce buildup that can affect seals.

Yes, stainless steel cups are generally compatible with a wide range of water-based and solvent-based paints, thanks to their chemical resistance. However, always check the paint’s compatibility with your specific cup material and seals. If in doubt, test on a small sample area and follow manufacturer guidelines to prevent reactions that could affect finish quality.

Pair a stainless steel 100mm cup with spray guns from Bosch or Total for compatible performance, or opt for generic spray gun kits that include a reliable cup and fittings. Articles like the 440W 800ml Bosch gun or TAT-series Total cups complement standard spray guns. For a complete setup, choose cups with matching nozzle sizes and thread patterns to ensure a tight seal and smooth spray.
