Abstract
Twin seals are provided between an end fitting and a convoluted hose connected thereto. The end fitting has two parts, one of which terminates in an elongated member having large and coarse threads on the outside thereof. As the elongated member is turned into the end of the hose, convolutions at the end of the hose are either scrunched and squeezed together or stretched over a ramp section. One of the seals is along the surface of the large threads and the other is a result of the end thrust either the scrunching and squeezing or the stretching of the end convolutions. A pilot end of braid on the hose pulls it to increase the end thrust. In some embodiments, a third seal is made between the outside surface of the hose and a gland surrounding the hose. The pitch of the large and coarse threads may be longer than the pitch of the convolutions so that an inner core of the hose advances faster than the outer braid, as the elongated member is turned into the end of the core thereby increasing either the scrunching and squeezing or the stretching.
