The Ripper Cap is built for fast fluid transfer—pouring about 5 gallons in under 1 minute when used as directed. Part RR20 from Tuff Jug is designed for top-load tanks so you can keep the jug upright while pouring.
Because flow is so high, the tank opening must stay clear and the ventilation line must be installed correctly in both the cap and jug handle. Confirm your jug generation and tank opening before ordering.
