ABSTRACT:
PRIOR ART
The invention relates to a radial sealing ring as and to a method for producing the sealing ring. Known O-rings of this generic type do not offer optimal mounting safety, because they can become twisted or notched in the mounting process.
ADVANTAGES OF THE INVENTION
A radial sealing ring according to the invention has extremely high mounting safety; that is, damage when the sealing ring is mounted or inserted and when the parts to be sealed off from one another are connected damage is precluded.
At the parts to be sealed, simple annular shoulders that are mounted on ends adjoining one another act as the sealing faces. The radial fixation is accomplished via the closed ends of the radial annular shoulder portions, engaging one another from above or putting one inside the other, of the parts to be joined to one another tightly.
Centering of the parts to be joined tightly together via the seal of the invention is made possible by an embodiment set forth herein.
An expedient method for producing a sealing ring according to the invention is recited hereinafter.
