To provided a small diameter tube joint for connecting small diameter tubes arranged in parallel, wherein the reduction in a mutual distance between neighboring small diameter tubes is materialized.
In a small diameter tube joint, a plurality of main bodies 1 provided with an accommodation chamber 10 opened to one surface side and a tube insertion hole 11 connected thereto and a plurality of seal rings 2 made of elastomer which are accommodated in the accommodation chamber 10 are arranged in parallel. In a state that the small diameter tube t is inserted into the tube insertion hole 11 after being fitted into the inner peripheral part of each seal ring 2, all seal rings 2 arranged in parallel are pressed in a thickness direction, thereby exhibiting the sealing function by pressure contact force between a constitutional wall surface of the accommodation chamber 10 and the seal ring 2 and between the small diameter tube t and the seal ring 2, and the tube retaining function by pressure contact force between the small diameter tube t and the seal ring 2, respectively.
