81 Cap

The 81 Cap is built for graffiti artists who need maximum coverage, speed, and reliability. Designed for cans with female valves, it fits 400ml, 500ml, and 600ml sizes, producing wide, solid, full-opacity lines between 40–60 cm — perfect for rapid fill-ins and bold, heavy tags.
Tested on a 400ml Montana Black can, the 81 Cap pulled off a double-hand fill-in across nearly 20 square metres in just 120 seconds, using only 8 cans — that’s a spray efficiency of 2.45 square metres per can and 0.16 square metres per second.
Made from tough, factory-injected plastic, the 81 Cap is reusable up to 30 times without losing performance, making it a serious tool for artists who don’t mess around.
