Sekt Cap Adapter-Pink- 
This is one solution for adapting male caps to a male can. These adapters will bridge the gap between the caps you love to use and many paint lines that have switched to male valve systems. Simply place this adapter over the valve system and insert your favorite male caps. Not unlike snoodling.

Pink - This cap adapter works with many american brands of male spray paint cans that have a narrower stem. We have tested it on Painters Touch, American Accents and Rustoleum. Keep in mind that these brands often use different valves for the same line and even the same color, this adaptor may not work with every can.
