Aerospace & Defense Underwater

Nortech’s Aerospace & Defense Underwater, Subsea, and Marine Cable Assemblies aren’t just rugged—they’re the steadfast conduits you need for your most challenging applications. With materials like custom elastomers and specialized urethanes, combined with our innovative use of super absorbent polymers for pressure control, our assemblies withstand not just any environment, but are designed with your environment in mind. Whether it’s depths that will crush ordinary cables or pressures demanding uncompromising reliability, our systems are designed to outperform expectations. Our hydrostatic testing ensures that every inch of the cable is crafted to withstand the pressure, ensuring the integrity of your mission-critical systems.

The trick in extreme environments isn’t just survival; it’s thriving. Our Penetrators, Connectors, and Bulkheads don’t just deliver connectivity—they’re your team’s silent partners, ensuring your technology keeps working when the rest of the world can’t.
