William Creavey opened the doors of progress by giving
the world a reliable way to close off potential leaks between mating
surfaces in static and dynamic applications.
An encapsulated o-ring is a two-component circular seal with a round
cross section. The elastomers impart memory to the seal and are encapsulated
in a Teflon jacket. The encapsulation protects the elastomer from
hostile environments.
Creavey Seal Company engineers and manufactures encapsulated o-rings
in two grades of Teflon and several elastomer materials with a hollow-core
version for specialized needs. The various combinations of these materials
cover a full spectrum of operating conditions in virtually every known
sealing application... with
many new applications on the horizon.
Compared with solid o-rings, Teflon-encapsulated o-rings function
in a broader range of environments. |

The homogeneously welded Teflon jacket with an energizer
imparts inherent memory to the o-ring. Each energizer varies in its
ability to return to its original shape when subjected to a compressive
force. Selecting the optimal material and dimensions depends on the
application and the specific requirements of the seal.
Creavey Seal encapsulated o-rings and pressure seals use three different
cores depending on temperature and operating conditions as well as
steel core Astra Seals, excellent for face seals in cryogenic applications,
such as liquid oxygen or hydrogen service. |
