The FlyDive hose bearing is the most rugged and advanced swivel on the market. With automatic flushing, you don't need to worry about sand or grit getting stuck in your ball bearings. Delrin bearing balls provide a hard and durable rolling surface for years of use, while stainless steel shoulder bolts and urethane rollers keep the bearing contained and rolling free in all situations. Hard and dimensionally stable delrin is used for the wear ring, accurately filling the water flow gap and reducing the water leakage while allowing free rotation of the bearing. Dual rings endow the hose nipple with a strong, positive lock whether using FlyDive's custom Saddle Clamping system, or more traditional band clamps.
