    • A fluid fitting for attachment to a tube includes a cylindrical first sleeve having a tapered outer end surface and an inner surface defining an axial bore for receiving the tube. A cylindrical second sleeve creates an annular space for receiving the tube between the first and second sleeves when the second sleeve is placed within the axial bore. The axial bore has substantially equal diameter throughout. A swage ring has a tapered inner surface that axially swages the swage ring to the first sleeve, second sleeve and tube. A first sleeve shoulder restricts axial movement of the swage ring. A first portion protrudes from the inner surface of the first sleeve to restrict axial movement of the second sleeve.
    • 用于附接到管的流体配件包括具有锥形外端表面的圆柱形第一套筒和限定用于接收管的轴向孔的内表面。 当第二套筒放置在轴向孔内时,圆柱形第二套筒形成用于在第一和第二套筒之间接纳管子的环形空间。 轴向孔径贯穿整个直径。 模锻环具有锥形的内表面,其将模锻环轴向地拧紧到第一套筒,第二套筒和管。 第一套筒肩限制了锻造环的轴向运动。 第一部分从第一套筒的内表面伸出以限制第二套筒的轴向移动。
