13に容易に接続できる。Next, the insertion port 16 of another pipe body 11 is inserted into the pipe body 11 on which the rubber ring 1 for piping is mounted, and the pipe bodies 11 are connected to each other. Is compressed, and the inner surface (reference surface 3) of the main body 2 of the rubber ring 1 and the lip portion 5 are brought into close contact with each other. When connected,
The pipe rubber ring 1 is formed with an inclined lip 5 and a tapered surface 15 at the end on the side of the insertion port 16 so that connection work can be easily performed. Can be compressed. At this time,
As shown in Table 1 above, the position of the thick rim 6 formed at the tip of the lip 5 is determined by the length of the reference surface 3 of the main body 2, that is, from the coupling portion with the lip 5. The distance A from the coupling portion of the lip 5 facing the reference surface 3 to the main body 2 to the thick edge 6 is substantially equal to the distance B to the edge 2c, that is, the ratio B of these distances: A
1: 0.95 to 1: 1.15, preferably 1: 0.9
Since it is formed in the range of 8: 1 to 1.05, the thick edge portion 6 is not compressed by the main body 2 and the insertion port 16 can be easily connected to the receiving port 13 when the pipe is connected.

る。As described above, when the insertion port 16 is inserted into the reception port 13 and connected, the outer peripheral surface 14 of the insertion port 16 is in close contact with the side surface of the lip portion 5 of the piping rubber ring 1 on the reception port 13 side. . When a force is applied in the pulling-out direction from this connection state, the lip portion 5 of the rubber ring 1 for piping does not bend while being in close contact with the insertion opening 16, and the thick edge portion 6 formed on the lip portion 5 Engagement with the edge 2c generates resistance, and the insertion opening 16 cannot be easily removed. As shown in Table 1 above, the pulling force required at the time of this pulling is determined by the pipe 11
Is approximately twice as large as the insertion force of the insertion opening 16 when connecting.

め、容易に抜脱ができない。Therefore, the rubber ring 1 for piping of the present invention thus constructed has a cross-sectional shape as shown in Table 1 above, in which the angle θ between the main body 2 and the lip portion 5 is 45-45.
The lip 5 is formed in a substantially V-shape of 60 °, and the shape of the lip 5 is slightly longer than that of the main body 2, that is, the inner diameter of the lip 5 when the outer diameter Dp of the insertion opening 16 of the tube 11 is 100. Since d is 85 to 92 and the thick edge portion 6 is formed at the tip thereof, when inserting and connecting the insertion port 16 to the receiving port 13, the lip portion 5 is formed to be inclined and Has a tapered surface 15 so that it can be easily inserted and connected in the same manner as in the related art. On the other hand, after the tube 11 is connected, the insertion port 16 is pulled out of the receiving port 13. When
The thick edge 6 of the lip 5 of the rubber ring 1 for piping is
And is located without being compressed in the gap between the groove 12 of the receiving port 13 and
Since the thick edge 6 is engaged with the edge 2c of the main body,
The lip 5 acts as a resistance in the pulling-out direction, so that the lip 5 does not deform in the pulling-out direction, and the lip 5 and the outer peripheral surface 14 of the insertion port 16 remain compressed.
Are in close contact with each other, the frictional force between the insertion opening 16 and the lip portion 5 of the rubber ring 1 for piping becomes large, that is,
Since the force required for pulling out is about twice as large as the insertion force, it cannot be easily pulled out.
