Upgrade your solvent trap setup with our Ultra Stepped Solvent Trap Cups, designed for a precise fit inside standard D sized tubes. These high-quality stepped cups offer dependable performance, easy handling, and strong long-term durability for solvent capture, cleaning support, and dry storage applications.
Perfect Fit for D Sized Solvent Trap Tubes
Our Ultra Stepped Solvent Trap Cups are engineered to fit smoothly inside D sized solvent trap tubes. Because of their precise design, they help create a cleaner, more organized internal setup. This makes them a popular choice for customers who want dependable solvent trap cups with a secure and consistent fit.
Thread-Together Design for Secure Dry Storage
Each cup threads together to help create a tight, water-resistant seal. As a result, these cups work well for dry storage and solvent trap maintenance needs. You can use them to help protect small valuables, organize essential items, or support proper cleaning solvent filtration during approved cleaning use.
This threaded design also makes each cup simple to install, remove, and maintain. Instead of dealing with loose parts or complicated assembly, you can quickly access the components when needed.
Aircraft-Grade Aluminum Construction
We manufacture these stepped solvent trap cups from premium aircraft-grade aluminum. This material delivers an excellent balance of strength, lightweight handling, and corrosion resistance. Therefore, the cups offer reliable performance without adding unnecessary weight to your D sized tube setup.
Aluminum also stands up well to regular cleaning tasks. That means you get a durable product built for repeated use, proper maintenance, and long-term value.
The thread-together cup design keeps installation fast and simple. You can assemble or remove the cups with minimal effort, which makes cleaning, inspection, and storage more convenient. Whether you are upgrading your solvent trap parts or replacing existing components, these D sized stepped cups provide a user-friendly solution.
Built for Responsible Solvent Trap Use
These Ultra Stepped Solvent Trap Cups are intended for lawful solvent trap, cleaning, and dry storage use only. Always follow all local, state, and federal laws, including all National Firearms Act regulations.
Do not modify solvent trap parts into a silencer, suppressor, or any regulated device without receiving proper legal approval first. Unauthorized modifications are illegal and may carry serious legal consequences. If you need a silencer or suppressor, purchase one through a licensed dealer and complete the required approval process.

So these stepped cups are way better that the regular ones. Not sure why other companies dont use this design but Im glad I have these. They fit just right in the tube I got from here too. Their machining is top notch for sure. I will be back for more from Freedom Gear
