Seal assembly method and apparatus

A seal assembly, comprising:

• a first conduit member having a first seat;
• a second conduit member having a second seat, the second conduit member coupled to the first conduit member such that a passage extends through the first and second conduit members along a longitudinal axis of the seal assembly and the first and second conduit members are moveable between at least two configurations, the at least two configurations including:
• a rest configuration in which the first and second seats are a rest distance apart, and
• a compressed configuration in which the first and second seats are held at a compressed distance apart, the compressed distance being less than the rest distance;
• and
• a flexible seal received between the first and second seats such that the flexible seal is compressed when the first and second conduit members are in the compressed configuration, the flexible seal expanding radially outwards when compressed to engage with an inner surface of a body in which the seal assembly is received, and
• wherein the flexible seal includes at least one adhesive sealing surface comprising adhesive arranged to engage with the inner surface of the body when the flexible seal is compressed.
