J-tube Seals
J-tube seals are used to seal the end of J-tubes, preventing seawater ingress and allowing injection of corrosion inhibitants, a solution which prevents corrosion within the J-tube structure.
Hengtong Marine customized J-tube seals come in both diver-less and diver-install type. Both designs utilized marine grade polyurethane to form an interference fit between the umbilical and J-tube interior. At the same time, our J-tube seals can act as centralizers, centering the umbilical along the J-tube axis and preventing excessive wear.
