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.
