O RING OD CANTILEVER SPRING ENERGIZED SEAL

When considering a rotary service seal and additional gland diameter is available, an O-Ring OD Seal provides a level of anti-rotation and redundant sealing. The addition of an O-Ring on the OD of a radial seal creates a high friction interface at the bore to counteract rotary forces. Because the O-Ring is a lower durometer than the jacket material, it is more compliant and offers tight sealing on the bore. This feature is utilized in equipment such as vapor recovery and vacuum pumps where running friction needs to be low and sealing efficiency high.
