Engineered and manufactured to UL standards by highly skilled technicians, our hermetically sealed assemblies and vacuum feedthroughs serve in military, aerospace, space simulation, Universities and semiconductor applications.

  • High-voltage protection.
  • Fiber optic cable
  • Low outgassing for vacuum use on BCE epoxy based parts
  • High vacuum ceramic to metal seal
  • High temperature ceramic to metal seals
  • Ruggedizing to marine and military specifications

All of our custom hermetic sealed assemblies are designed and manufactured to the highest quality and compliance standards (NASA ASTM E595). All are 100% electrically and vacuum leak tested before leaving our facility. And we can design and ship products that comply with ITAR, DDTC, DFARS, Conflict Minerals, ROHS and UL requirements.

Plug Feedthrough

Plug Feedthrough

Simply-designed, versatile and robust!


Permanently sealed with durable BCE epoxy, hermetic wire feedthroughs, circular plastic, Mil-C, coaxial, waterproof, thermocouple, high current, and high voltage connectors.

BCE cable harnesses support many different combinations of hermetic feedthrough connectors on the vacuum and atmospheric sides accommodating multiple conductors.

BCE epoxy sealed to eliminate all leaks (stranded wires included), BCE assemblies feature meticulous-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.

BCE custom hermetic cable harnesses can withstand a range of operating environments, including vacuum from 1x10-10 cc/sec He.

  • Medical imaging systems
  • Space simulation and aerospace
  • Military applications
  • Oil and gas, alternative energy
  • Semiconductor manufacturing
  • Automotive fuel pumps
  • Air conditioning compressors
Plug Feedthrough

High Temp 16 Pair Type J T/C Feedthrough

High temperature, vacuum sensor array used in the Aerospace industry.


High temperature environments require vigorously designed seals for ultra-high vacuum (UHV) and high-temperature atmospheres. BCE incorporates the use of both metalized ceramics and active alloy sealing methods. This offers our customer’s the most suitable design for their applications.

With various KF and CF flanges, BCE can build and test your application with certification of 1x10-10 cc/sec He and operating temperatures up to 300°C near the feedthrough seal. The bake-out temperature can be as high as 450°C.

Learn what a vacuum feedthrough is here.

Equipment manufacturers and scientific researchers are continually challenged with supplying power, fiber-optic, control, and monitoring cables into (and out of) sealed vacuum vessels. Whether due to space restrictions, special geometries, or number and type of conductors, standard glass-to-metal or ceramic feedthroughs never quite fit the bill. Unfortunately, because of limited options, many designers are forced to compromise and go for an off-the-shelf solution.
