Douglas Electrical Components designs hermetic feedthroughs for immersion-cooled data centers, sealing connections like RJ45, USB, fiber, and power studs against dielectric fluids. Unlike standard IP-rated solutions, hermetic seals provide long-term protection, improved reliability, and custom mechanical integration for high-density server environments. Read more...

Hermetic feedthroughs are essential for TVAC space simulation, maintaining vacuum integrity while transmitting power and signals. Douglas Electrical Components provides PotCon® and PortPlate solutions using NASA-certified epoxy, supporting high-density, cryogenic, and fully tested assemblies for critical projects like the Dragonfly Titan mission. Read more...

NPT feedthroughs use tapered threads for simple, cost-effective sealing in electrical systems. Douglas Electrical Components offers hermetic NPT solutions for power, signal, and fiber transmission in vacuum, pressure, and hazardous environments, with customizable designs and explosion-proof options. Read more...

JacketSeal™ feedthroughs provide water- and fluid-tight sealing for applications where hermetic sealing isn’t required. Using epoxy bonding, they protect cables and connectors in harsh or submerged environments, supporting IP-68 and explosion-proof standards with flexible, customizable designs. Read more...

Conax HEGPK high performance electrode feedthroughs electrically and/or thermally insulate single electrodes, tubes, temperature sensors and other elements while passing into a vacuum or pressurized environment. HEGPK features a single piece insulator manufactured from PEEK™, one of the highest performing engineered thermoplastic materials available. Read more...

Conax Technologies’ EGT feedthroughs electrically and/or thermally isolate single electrodes, tubes or temperature sensors for use in vacuum furnaces, liquid level probes, transformers, environmental chambers, power leads and more. EGT feedthrough insulators and sealants are provided as a single continuous Teflon™ piece to accommodate higher voltage/amperage at lower pressures. Read more...

Douglas Electrical Components’ CF flange feedthroughs provide reliable hermetic sealing for vacuum systems using a copper gasket clamping design. Supporting connectors, wires, cables, and fibers, they offer high-density, space-saving solutions with flexible configurations for power and signal transmission in demanding environments. Read more...
