Abstract
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.
