Patent ID: 6860522

Claim:
A connector fitting ( 3 ) for a high pressure hose ( 1 ), with a connecting element that has a profiled nipple ( 7 ) on one end, that is inserted in an end of a high pressure tube ( 2 ), whereby the high pressure tube ( 2 ) is sealed in an annular gap located between an outside of the nipple ( 7 ) and an inside of a clamping sleeve ( 9 ) that is pressed onto the connecting element ( 4 ), the connecting element ( 4 ) and the high pressure hose ( 2 ) are held tightly sealed in the annular gap and are rotatable with respect to one another, wherein the connecting element is formed of at least two pieces and includes a connecting element part ( 4 ) that has the nipple on one end and threads on another end thereof, and the threads are engageable with mating threads from a coupling element selected from a plurality of different coupling elements that are removably connectable to a mating coupling for the high pressure hose, the threads and their mating threads are screwed together up to a stopping point, and a back end ( 15 ) of the connecting element or the coupling element ( 4 , 5 ) that contains internal threads cooperates with a circular shoulder ( 12 ) on the other fitting element ( 5 , 4 ) that serves as the stopping point, at least in areas, the circular shoulder ( 12 ) and the back end ( 15 ) containing the internal threads have flat surfaces that come into sealed contact with one another, and the circular shoulder ( 12 ) and the back end ( 15 ) containing the internal threads include conical surfaces ( 23 , 24 ) facing one another or are designed as conical surfaces, that have different conical angles such that only outer annular regions of the conical surfaces ( 23 , 24 ) come in sealed contact, and a residual gap is provided between the circular shoulder ( 12 ) and the back end ( 15 ) into which to insert a sealant.
