A fiber optic feedthrough module which comprises a metal sleeve, a fiber optic element extending through the sleeve relation thereto, and a tandem series of centrally-apertured mating annular sealant bodies of thermoplastic material surrounding the fiber optic element and compressed between it and the sleeve. The module is made by first providing a loose sub-assembly of a plurality of individual but interfitting sealant bodies on the fiber optic element and then inserting this subassembly into a metal sleeve, followed by swaging the whole assembly which eliminates clearances and provides sealed interfaces between the various contacting components. |
