Further, also wrap seal ring, described seal ring between described the second hold-down ring and the second connecting tube, described seal ring described the second connecting tube of fitting.
Further, also comprise the first pad; Described the first pad between described seal ring and the second connecting tube, described the first pad described the second connecting tube of fitting.
Preferably, described the first hold-down ring and the second hold-down ring are metal spring.
Preferably, described the first core pipe and the second core pipe are metal thin-wall sleeve pipe.
Further, also comprise the first nut and the second nut; Described the first nut and the second nut are enclosed within respectively on described the first connecting tube and the second connecting tube.
Further, more fastening for pipeline is connected, also comprise metal cap, described metal cap is connected to described the second nut inwall.
Further, between described the first connecting tube and the second connecting tube, be provided with the second pad.
Preferably, the diameter of the first core pipe is 10mm, and the diameter of described the second core pipe is 20mm.
The beneficial effects of the utility model are: the utility model is simple in structure, install easily, can make tubing be connected with the utility model tightr, can seepage, also can not damage tubing itself.
