Since Urocare's “High-Flow”Little Red Valve serves not only as an anti-reflux valve, but as a gasket-ring as well, in circumstances where the valve is not used, this gasket-ring must be used in place of the valve to prevent leaks in all Urocare Reusable Latex Leg Bags and Urocare Urinary Drainage Bottle which incorporate this valve.
