Ductorseal hermetic feedthroughs from Douglas Electrical Components are sealed wire and cable assemblies that solve through-bulkhead conductor sealing problems in small-engine fuel-delivery modules. The units provide an interconnecting harness in a fully sealed, prewired, pretested, and ready-to-install hermetic unit. They feature a precision-machined, chemical-resistant epoxy housing with no mold parting line which could compromise O-rings and cause potential leak paths. They come in a range of standard housing sizes and configurations as well as with various numbers and types of conductors. The devices are epoxy-sealed to provide leak-free performance.
