Summary:Fire-resistant stuffing box for static elongate elements compressing a metallic annular body 1 comprising fastening means 2, 3 on either side of the wall 4 to be passed through and having a progressive internal narrowing 5 for axial blocking with compression of an annular sealing gasket 6 as well as an annular member 7 for compressing the gasket, characterised in that the sealing gasket 6 is composed of a multitude of coaxial layers of expanded graphite compacted into an annular preform part then shaped by compression, in the stuffing box itself, against the narrowing 5 and the elongate element 8 by the compression member 7, then held under a compression force. PRESSE-ETOUPE COUPE-FEU POUR ELEMENTS ALLONGES STATIQUES COMPRESSANT UN CORPS ANNULAIRE METALLIQUE 1 COMPORTANT DES MOYENS DE FIXATION 2, 3 DE PART ET D'AUTRE DE LA PAROI 4 A TRAVERSER ET PRESENTANT UN RETRECISSEMENT INTERIEUR PROGRESSIF 5 DE BLOCAGE AXIAL AVEC COMPRESSION D'UNE GARNITURE D'ETANCHEITE ANNULAIRE 6 AINSI QU'UN ORGANE ANNULAIRE 7 DE COMPRESSION DE LA GARNITURE, CARACTERISE EN CE QUE LA GARNITURE D'ETANCHEITE 6 EST CONSTITUEE PAR UNE PLURALITE DE COUCHES COAXIALES DE GRAPHITE EXPANSE COMPACTEES EN UNE PREFORME ANNULAIRE PUIS CONFORMEES PAR COMPRESSION, DANS LE PRESSE-ETOUPE LUI-MEME, CONTRE LE RETRECISSEMENT 5 ET L'ELEMENT ALLONGE 8 PAR L'ORGANE DE COMPRESSION 7, PUIS MAINTENUE SOUS UN EFFORT DE COMPRESSION.
