We deliver equivalent quality of umbilical diving equipment at market-leading prices, with full customization available.
The correct umbilical configuration depends on what must be transferred between the surface station and the diver. A basic system may only require breathing air and communication, while more complex commercial diving operations can also require pneumo depth measurement, video transmission or hot-water supply. Use the comparison below when evaluating a diving umbilical for sale for your surface-supplied diving system.

| Recommended Selection Scenario | Select when the system only requires breathing air and diver communication and a 7.5 mm breathing-air hose matches the required configuration. | Select when only breathing air and communication are required but the system specification calls for a larger 3/8-inch breathing-air hose. | Suitable when breathing air, communication and a dedicated pneumo hose for depth measurement are required, using the smaller air- and pneumo-hose configuration. | Select when the operation requires air, communication and pneumo functions together with 3/8-inch breathing-air and 1/4-inch pneumo hoses. | Recommended when surface personnel also need video transmission for underwater inspection, monitoring or recording in addition to air, communication and pneumo functions. |
Choose a 2-part umbilical when air and communication are the only required services.
UMB002 and UMB021 both combine a breathing-air hose with a communication cable. The main selection difference is the breathing-air hose size: UMB002 uses a 7.5 mm nominal bore, while UMB021 uses a 3/8-inch / 9.5 mm nominal bore. The required hose specification should therefore be confirmed against the diving system before ordering.
Choose a 3-part umbilical when pneumo depth measurement is also required.
UMB003 and UMB031 add a separate pneumo hose to the breathing-air and communication lines. UMB003 combines a 7.5 mm air hose with a 5 mm pneumo hose, while UMB031 uses a 3/8-inch / 9.5 mm air hose and a 1/4-inch / 6 mm pneumo hose.
Choose UMB004 when underwater video must be integrated into the diver's lifeline.
In addition to breathing air, pneumo and communication, UMB004 incorporates a video cable with RG-59 coax and electrical conductors for camera and lighting connections. This configuration is suitable when surface teams require real-time visual monitoring or recording during underwater work.
Choose UMB005 when the diving system also requires hot-water delivery.
UMB005 adds a 1/2-inch hot-water hose to the air, pneumo, communication and video lines. It is the most comprehensive configuration among these six models and is designed for professional surface-supplied diving operations where hot-water supply is required in cold-weather conditions.
Before specifying an umbilical, confirm the required breathing-air hose size, pneumo line, communication system, video equipment, hot-water requirement, fittings, operating length and termination arrangement. SEAM can then match the appropriate model and configuration to the surface control system and intended diving operation.
