A zero-flow thread-lock quick connect/disconnect coupling having male and female couplers that enhance the fire-resistance capability of the coupling in a zero-flow pressurized state. The couplers include a fire-resistant seal assembly including a seal ring and non-metallic backup rings disposed. A first backup ring is made with a high-temperature non-metallic material and is formed as a delta ring for enhancing sealing performance during a fire event. A second non-metallic backup ring is formed as a half-delta ring between first and third backup rings. The third backup ring is made with a non-metallic material that is softer than the first and second backup rings and which abuts the seal ring. The female coupler includes a bearing ring that operatively connects a rotatable threaded support to the coupler body, a protrusion-slot interface between an actuating sleeve and the rotatable support, and a seal in the actuating sleeve for damping and/or debris-resistance.

A fire seal end cap including a cap portion and a plug portion, wherein the plug portion protrudes from the cap portion, and wherein the cap portion and the plug portion are formed from a fire-resistant material.

The present disclosure relates generally to systems for providing a durable water-resistant and fire-resistant foam-based seal in the joint between adjacent panels. A fire-resistant and water-resistant expansion joint seal is provided which includes one or more foam members and a plurality of intumescent members interspersed within the foam member or members to provide a spring recovery force and fire resistance.

Knit fabrics having ceramic strands, thermal protective members formed therefrom and to their methods of construction are disclosed. Methods for fabricating thermal protection using multiple materials which may be concurrently knit are also disclosed. This unique capability to knit high temperature ceramic fibers concurrently with a load-relieving process aid, such as an inorganic or organic material (e.g., metal alloy or polymer), both small diameter wires within the knit as well as large diameter wires which provide structural support and allow for the creation of near net-shape preforms at production level speed. Additionally, ceramic insulation can also be integrated concurrently to provide increased thermal protection.

A sealing arrangement at an interface between a combustor and a turbine of a gas turbine. The turbine can include deflecting vanes at its inlet, which deflecting vanes are each mounted within the turbine so as to define an inner or outer diameter platform and are in sealing engagement via an inner or outer diameter vane tooth with a seal arranged at the corresponding inner or outer diameter part of the outlet of the combustor. The seal is movable and is pressed on the inner or outer diameter vane tooth by a differential pressure such that the pressure of the mainstream hot gas flow is a lower pressure.
