Flexible hose and fittings

摘要

A flexible hose has ribbed portions concatenated with cylindrical smooth portions. The ribbed portions provide flexibility and resilience to the hose. Flotation cuffs for buoyancy and wheel cage cuffs for reducing friction are mounted on selected smooth portons of the hose. A fitting removeably attaches to a ribbed portion forming the end of the hose to allow rotatable attachment of the hose to other apparatus.
