Our new Hose Swivel O Ring has been designed to alleviate the flow of water around the Zapata Racing Hose Swivel Connection. As a replacement to the Standard Hose Swivel Wear Ring, this rubber O Ring seals off the flow of water outside of the Swivel Connection which improves performance of the attachment be it a Flyboard, Hoverboard, JetPack or other Hydro Sports Device that connects to the ZR Hose Swivel.
