The large hole at the inner side is a flared hole (7) with the large opening facing inside.

A spacing is formed between the inner wall of the flared hole (7) and the pipe (1) to be connected.

The groove of the connector body of the connecting pipes is formed directly on the inner wall of the flared hole, so it can prevent the connector body from generating a large curvature change in a short length.

The large hole at the inner side is a flared hole (7) with the large opening facing inside.

A spacing is formed between the inner wall of the flared hole (7) and the pipe (1) to be connected.

It was usually wider on the outside, so the hole flared out.

The rigid base (1) of the solid pad is cone-shaped, while the base of the hollow pad is rounded on the edge, the central hole being slightly flared at the base.

A flared fitting embodiment is also provided.

The head may be disposed in the tapered hole and may have a wall having a taper at substantially the same angle as the tapered hole.

A hammer head is releaseably mounted to the flared mount.

The flared connector forms a catheter connector end (21).

The flared port (6) is provided in the top end of said immersing pipe.

The distal piston-sealing element is flared in the direction of piston downstroke and the proximal piston-sealing element is flared in the direction of piston upstroke.

The end cap is connected to the through pathway, and has a tapered bore.

A continuous horn or flared radiator antenna system is provided.
