What Is A Cone Seal

The conical seal is generally in the form of contact seal between the conical bell mouth and the conical boss. The size is very small, so gaskets or sealing rings cannot be used, and it needs to bear high positive and negative pressure.

Sealing principle of conical seal:

For the connection and sealing between the conical bell mouth and the boss, screw in the coupling nut first to make the outer cone surface of the boss contact the inner cone surface of the bell mouth to form a line seal for positioning. Then screw in the coupling nut and apply the pre tightening force, and the bell mouth will be elastically deformed. With the increase of the force, the bell mouth will be plastically deformed, and the gap between the bell mouth and the boss will be filled to finally achieve sealing.
