Proposed tubular gasket for doors performs dual function: seals in pressure, and seals out heat. Composed of quartz fabric filled with alumina matting, gasket is bonded with room-temperature-vulcanizing material to periphery of door. When door is closed, gasket is compressed like O-ring: fills gap between door and frame; and prevents leakage of air and heat.
