A seal assembly includes an outer member defining a bore and an inner member received in the bore of the outer member and one of the outer member and the inner member defining a shoulder portion. An inner circular cross-section metallic ring member and an outer circular cross-section metallic ring member are disposed between the outer member and inner member and against the shoulder portion. A wedge member engages the inner circular cross-section metallic ring member and the outer circular cross-section metallic ring member for applying an axial force against each of the inner and outer circular cross-section metallic ring members in a direction toward the shoulder portion and for applying a radially outer force against the outer circular cross-section metallic ring member and for applying a radially inner force against the inner circular cross-section metallic ring member.

An adapter for joining a sprinkler to a pipe element has a body with outer flat surfaces and grooves that receive seals. A plug for sealing a pipe element has a cylindrical body with a circumferential groove which receives seals. Both the adapter and the plug fit within the pipe element and are secured and sealed by a deformation formed in the pipe element by a circumferential groove. The deformation mechanically engages the grooves in the body of the adapter and the plug.

The present disclosure is directed to a seal assembly for a propulsion system. The seal assembly couples a plurality of manifolds of a manifold assembly of the propulsion system generally in fluid communication. Each of the manifolds defines a first end and a second end. The seal assembly includes a coupling member attaching the first end and the second end of the manifold assembly together in fluid communication; one or more seals disposed between the coupling member and at least one of the first end and the second end of the manifold; and a retainer adjacent to the coupling member and the seal. The retainer defines a radial wall and an axial wall, in which the radial wall is extended generally from one or more of the first end and the second end of the manifold alongside the coupling member and the seal, and the axial wall is extended generally from the radial wall alongside the coupling member and the seal.
