Hermetic Electrical Feedthroughs
Hermetically seal virtually any conductor or optical fiber
Hermetic electrical feedthroughs create a gas and liquid tight seal that is safe to use in sealed environments. For 80 years, Douglas Electrical Components has provided interconnect solutions with a selection of custom hermetic seals and feedthroughs designed to meet application demands such as high pressures, necessary leak rates, and more. Douglas’ hermetic feedthroughs allow virtually any power and signal wires, cables, connectors, or circuits to pass into sealed enclosures without any worry for leakage through or around the electrical connection.
Our portfolio creates unmatched design flexibility and optimal performance in harsh environments. Integrate pins, circuits, harnesses, and more directly into your hermetic electrical feedthrough design from single piece projects to OEM, high-volume quantities. Our engineers partner with you to select high-quality components and have the flexibility to customize the mechanical interface or hermetically seal within your existing design.

WIRE, CABLE & OPTICAL FIBER
Design and manufacture various wire and cable solutions including feedthroughs and harnesses. We offer the unique ability to hermetically seal wires, conductors, and optical fibers using high-strength epoxy, creating hermetic solutions for hazardous and non-hazardous applications.
CONNECTORS & CIRCUITS
Hermetically sealed connectors can be designed with virtually any conductor, circuit, or fiber. The mechanical interface can include existing connector hardware, custom flanges, or customer-specific designs. Design power, signal, or hybrid connector packages that are hermetically sealed and moisture-tight.
HERMETIC TERMINAL SEALS
Douglas manufactures both standard and custom hermetic terminal seals for power applications including compressors and motors. From threaded designs to custom plate assemblies, Douglas will manufacture a hermetic terminal seal in the exact configuration required.
