DuctorSeal® wire and cable assemblies incorporate custom wire harnesses in hermetically sealed feedthroughs that have been pre-wired and pre-tested.

DuctorSeal cable harnesses support many different combinations of connectors on the vacuum and atmospheric sides and can accommodate conductor counts of up to three thousand wires.

Epoxy sealed to eliminate all leaks—even in stranded wires—DuctorSeal assemblies feature precision-machined housings of aluminum, titanium, steel, brass, plastic or low outgassing epoxy. The seals are available with standard or custom bundles composed of wires and cables ranging in size from AWG 38 to 500 MCM.

DuctorSeal can withstand a range of operating environments, including vacuums from 1x10-10 Torr to pressures of 15,000 psi. Operating temperatures range from 4 K (LHe) through 200°C. High voltage and low cross-section wire feedthroughs operating up to 30kV-DC are also available.
