Divex twisted umbilicals are the choice of diving professionals including construction, police, and saturation divers worldwide.

Twisted umbilicals offer significant advantages including great flexibility and strength while resisting kinking, and abrasion due to the inherently strong ‘rope-like’ structure.

Unlike rubber or PVC compounds, used previously for diving umbilicals, the hoses are made predominantly from polyurethane. This is a particularly clean unfilled polymer containing no plasticisers or potentially harmful additives. This ensures breathing gas quality is maintained under all conditions from -400C to +600C. In addition, polyurethane does not deteriorate significantly with age thereby easily outlasting rubber and PVC type hoses.

Divex manufacture and stock the most popular style of three element air diving umbilical (gas, comms, pneumo), with 50mtr, 75mtr, and 100mtr lengths normally ready to go the same day. Variations on umbilical end fittings, length and additional cables or hoses are of course available upon request.


In 2015 James Fisher Defence and Divex merged to form JFD.
