The Mirka Paint Cup System 125 µm Filter Lid, Model 9190170650, is a disposable paint cup system built for spray gun setup, paint mixing, and paint application. This is a paint cup system designed for spray finishing and refinishing work. If you want a cleaner, faster way to mix material, mount it to a spray gun, and keep moving through prep and spraying without fighting cleanup, this system is aimed right at that job.

What matters here is that this is not just a loose cup or a replacement lid. It is a complete Mirka system that includes 50 disposable liners and lids with a 125 µm filter, 20 stoppers, 1 rigid outer cup, and 1 retaining ring. In practical terms, that gives painters a ready-to-use setup for repeated spray sessions while keeping the working cup disposable where it counts. The 125 µm filter helps catch contamination before material reaches the gun, which is a real advantage when finish quality matters.

The design is straightforward and job-focused. The rigid outer cup supports the liner during mixing and spraying, while the retaining ring secures the assembly. That kind of setup helps keep handling simple at the bench and at the booth. For shops trying to stay organized, a disposable liner system also cuts down on wash-up compared to reusing traditional hard cups for every batch.

Mirka also calls out that all parts are resistant to corrosion from paint and thinner. That matters because cup systems live around aggressive materials, not clean showroom conditions. If a system cannot handle regular exposure to coatings and solvent, it becomes a weak link fast. This one is built with that real-world environment in mind.

For compatibility, the system is intended to mount on a spray gun, but the adapter must be purchased separately. That is an important buying detail. If you are setting up a new spray gun or replacing an older cup system, make sure you have the correct adapter for your gun before you start. Once paired properly, this type of setup is well suited to consistent material handling and cleaner workflow in automotive refinishing and similar paint applications.

Who should buy it? Painters, body shops, refinishing techs, and serious DIY users doing spray work will get the most from it. If you spray often enough to care about cleaner material flow, faster changeovers, and less cleanup between colors or products, this Mirka paint mixing and spray cup system makes sense. If you only spray once in a while, it still has value, but the biggest payoff shows up in repeat-use shop environments where time and finish quality both matter.
