The Mirka Stainless Steel PCS Spray Gun Adapter, model 9190171113, is a stainless steel spray gun adapter for connecting a paint cup system to a spray gun. This is a spray gun adapter designed for paint cup system connection in automotive finishing. If you are building out a Mirka paint mixing and spraying setup, this is the small part that makes the system work the way it should.

What matters here is fit and chemical resistance. An adapter like this sits right between the spray gun and the cup system, so it sees regular exposure to coatings, solvents, and thinner. Mirka calls out corrosion resistance to both paint and thinner, which is exactly what you want in this category. That helps the adapter hold up in day-to-day finishing work instead of becoming the weak link in the setup.

The stainless steel construction is the practical selling point. In a paint environment, parts get wiped down, exposed to overspray, and handled often during cup changes and cleaning. Stainless steel makes sense because it is better suited for repeated contact with finishing materials and shop chemicals than a basic plated fitting that can degrade over time.

This adapter is part of the Mirka Paint Mixing range, which includes mixing cups, lids, systems, and dispensers aimed at automotive finishing professionals. In plain terms, that means it is meant to work inside an organized paint prep workflow, not as a random universal fitting. The benefit is cleaner integration between the cup system and the spray gun when the correct adapter size is chosen.

This specific listing is size 13. That detail is important because spray gun adapters are not one-size-fits-all. Buyers replacing an existing adapter or setting up a new paint cup system need to match the correct size to their spray gun connection. Getting that right saves time, avoids leaks or poor seating, and keeps the cup system secure during spraying.

If you work in collision repair, refinishing, or any professional paint environment where quick cup changes and consistent spray setup matter, this Mirka PCS spray gun adapter is the right kind of part to buy once and keep in rotation. It is especially useful for painters already using Mirka paint mixing products and looking for the proper interface between the cup system and a compatible spray gun.
