Abstract: A seal assembly, including a first conduit member having a first seat and a second conduit member having a second seat. The second conduit member is coupled to the first conduit member such that the first and second conduit members are movable between at least 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 is less than the rest distance. The seal assembly also includes 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 axially outwards when compressed to engage with an inner surface of a body in which the seal assembly is received.
