Patent ID: 8550504

Claim:
A fluid fitting for attachment to a tube, comprising: a cylindrical first sleeve having a tapered outer end surface and an inner surface defining an axial bore for receiving the tube, wherein the axial bore has substantially equal diameter throughout; a cylindrical second sleeve that creates an annular space for receiving the tube between the first and second sleeves when the second sleeve is placed within the axial bore, wherein an inner surface of the second sleeve defines another axial bore having a substantially equal diameter throughout; annular grooves protruding from the inner surface of the first sleeve and an outer surface of the second sleeve, wherein the annular grooves of the first sleeve and the annular grooves of the second sleeve overlap each other when the second sleeve is placed within the axial bore, a second groove protruding from the inner surface of the first sleeve formed prior to insertion of the cylindrical second sleeve, wherein the second groove overlaps a second sleeve shoulder provided on a lengthwise end of the cylindrical second sleeve that protrudes higher from the outer surface of the second sleeve than the annular grooves when the second sleeve is placed within the axial bore first, and the second sleeve shoulder is slideable along the inner surface of the cylindrical first sleeve; and a swage ring having a tapered inner surface adapted to axially swage the swage ring to the first sleeve, the second sleeve and the tube.
