- Conical Spring
These seals have a conically shaped spring, to secure the head and grip the shaft. They have o-ring mounted faces. There are a variety of of different comical spring seals, so we focus on identifying the different types of seal heads in order to guide you to the correct seal.
The sealing face is a separate ring of material, usually CAR, SIC or TC, that is not part of a solid, monolithic head but is inserted and securely held with a heat-shrink process, or is retained by an o-ring.
