The seal is secured to the host line by integral clamps. It can then be pulled into the J-Tube or I-Tube with the host line. Typically the seal will be installed in the J-Tube just behind the entry bellmouth.
Polyurathane seal elements are used to provide an interference fit to hold the host line and the J-Tube bore. The interference fit provides the seal - no subsea activation is necessary.

J-Tube seals are primarily used to prevent the loss of corrosion inhibitor within the J-Tube annulus.
