Rubber o ring is an o-ring which is mad of rubber.
An O-ring is a round ring that is used as a gasket for sealing a connection. O-rings are typically constructed out of polyurethane, silicone, neoprene, nitrile rubber or fluorocarbon. These rings are commonly used in mechanical applications, such as pipe connections, and help to ensure a tight seal between two objects. O-rings are designed to be seated in a groove or housing that keeps the ring in place. Once in its track, the ring is compressed between the two pieces and, in turn, creates a strong seal where they meet.
A ring allowing a longer length of an arm attached to a ring main body is provided. The tilted ring is tiltingly attached to the ring main body. The tilted ring is in an ellipse shape, and the major axis of the ellipse projected on the plane where the ring main body exists is longer than the diameter of the ring main body.
Thus, if the ring main body is worn on the finger on which a wedding ring or the like is already worn, the tilted ring does not interfere with the wedding ring. Thus, since the tilted ring can extend downward in addition to upward of the ring main body, the tilted ring can be longer, and the esthetic appearance increases.
