A method for checking a connection seal between two elements of a part, includes dipping the part to be checked in a penetrant having a compound suitable for reacting to light excitation; cutting the part at the connection to be checked; and checking for the presence of penetrant under a light capable of exciting the penetrant.

A dual seal termination assembly having a first termination body; and a sleeve at least partially surrounding the first termination body; primary and secondary seals adapted to be fitted between the first termination body and the sleeve; a test port in the first termination body to supply test fluid to a point between the primary and secondary seals of the first termination body; the test port being adapted to receive test fluid at a predetermined pressure, such that a pressure difference is created between the point between the primary and secondary seals and a point on the other side of the primary seal and a point on the other side of the secondary seal.
