Abstract
An assembly having a dual barrier gasket located at an interface between a first body and a second body is disclosed. The dual barrier gasket may include a substantially cylindrical inner surface. The dual barrier gasket may further include a gasket outer surface that is configured to provide an inner sealing barrier and an outer sealing barrier, where a first tangent plane to a portion of the outer sealing barrier is radially offset from a second tangent plane to a portion of the inner sealing barrier. The gasket outer surface may include a first port and a second port. A channel may extend from the first port through the dual barrier gasket to the second port. The first body (or the second body) include a channel extending from a cavity between the two sealing barriers of the dual barrier gasket and the first body (or the second body) to an external port.
