J-Tube Seals

Tekmar J-Tube Seals provide pressure retention within a J-Tube and clamp to the cable or umbilical centralising the product. The seal provides a long term barrier, prohibiting corrosion by preventing seawater from entering the J-Tube. In addition, the seal clamp provides a reaction interface to attach a train of bend restrictors in order to protect the cable or umbilical from overbending in the free span.
