Custom Pneumatic Umbilical Cable

Pneumatic umbilical cables combine air or gas transmission tubes with power, fiber optic and signal conductors in a compact cable structure for underwater control and monitoring systems. They are commonly used in inspection ROVs, scientific instruments, subsea sensors and offshore equipment requiring reliable pneumatic control in dynamic marine environments. For underwater robotic applications, pneumatic transmission can be integrated into a complete ROV Umbilical Cable solution.

We provide fully customized pneumatic umbilical cable solutions with flexible tube configurations, electrical and optical integration, and durable jacket materials engineered to meet your specific application, installation and environmental requirements. For projects requiring integrated power, fiber optics and fluid transmission, explore our Hybrid Subsea Cable solutions.
