Abstract
A respiratory access assembly may include a manifold having a first mating surface defining a first port opening. The respiratory access assembly may include a rotatable adapter having a second mating surface defining a second port opening and a seal assembly disposed between the manifold and the rotatable adapter that includes a first seal ring, a second seal ring, and an outer seal ring disposed proximate an outer perimeter of at least one of the manifold or the rotatable adapter. The rotatable adapter may be rotatable relative to the manifold between an open configuration and a closed configuration. The seal assembly may include a connection portion connected between the first seal ring and the second seal ring. The connection portion may form a seal between the first mating surface and the second mating surface between the first seal ring and the second seal ring.
