The Art Primo EZ Cap is a FEMALE cap that is versatile and thin. It's good for outlining and detail work. It has a nice comfortable feel. This cap is pressure sensitive and fairly controllable. It feels like a German Outline 2 on a Molotow Premium can. This cap works on many spray paint brands that have MALE valves. We have tested it extensively on Rustoleum Painters Touch male cans with great results.
*UPDATE* We have been informed by our customers in Asia that the AP Female Fat and the EZ Rider will fit large stem paints (Scotch Gaurd type) like Bosny and Pylox. Currently these are the only female caps we know of compatible with these International brands
