Boston Fat Caps
The Boston Fat Cap, is a fresh take on a classic cap. Fits perfectly on older Rustoleum female valves, and flows great with an adapter on new Rusto cans.
There’s something unique about this cap’s ability to handle Rustoleum’s throughput without leaking, giving you the ability to fully utilize the high output of Rusto’s spray line. Large flare tags are no problem with these caps and your favorite adapter.
NOTE: This cap does not fit directly on any modern popular spray paint brands however, it works great on American paint used with an adapter.
