<p>PURPOSE:To easily perform connecting work of tubes by engaging a rotary joint having a fluid tube connecting part and a joint connecting part with a rotary joint connecting part provided to a joint body having the fluid tube connecting part through putting a snap ring into a space formed through joining an annular groove. CONSTITUTION:A tube fitting 1 has internal threads on its both sides and is constituted so that a rotary joint connecting part 3 on one side of a joint body 2 having an internal thread of a liquid tube connecting part 10 on another side is rotatably engaged with a joint connecting part 5 on one side of a rotary joint 4 having an internal thread on another end. The rotary joint 4 has the joint connecting part 5 provided with a fitting groove 6, in which a snap ring 7 is to be inserted. The snap ring 7 is fitted into an annular groove 8 and makes the rotary joint 4 engage rotatably with the joint body 2. On the rotary joint 4, an 0-ring 9 is provided on the top end of the joint connecting part 5 for keeping air tightness. As a result, connecting work of tubes can be performed very easily regardless of length and shape of the fluid tubes.</p> |
