Experience unmatched performance with the HYDRA (Version 2), the new benchmark for ultra-wide spray caps. Engineered specifically for high-pressure spray cans like MTN Mad Maxxx, Montana Ultra Wide, Rustoleum Turbo 750ml, and Flame Booster 600ml, this cap seriously takes these cans to the next level in output.
Key Features:
