  • Systems and methods for applying ring shaped seal members
    Patent number: 6694591
    Abstract: Systems and methods are provided for the placement of ring shaped seal members on mechanical housings. In accordance with a preferred exemplary embodiment of the invention, a tapered insertion tool is placed over a mechanical housing on which a ring-shaped seal member is to be located. The ring-shaped seal member is then placed on the tapered insertion tool. A further insertion device is moved over the tapered insertion tool and an inner tubular portion pushes the ring-shaped seal member body over the tapered insertion tool. An outer tubular portion of the further insertion device advantageously prevents the ring-shaped seal member body from rolling during the insertion process.
