Abstract
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.

A dual seal termination assembly, the assembly comprising:
- a first termination body;
- 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 a test fluid to a point between the primary and secondary seals of the first termination body;
- the test port being adapted to receive the 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 an other side of the primary seal and a point on an other side of the secondary seal;
- a second termination body wherein the sleeve is connected between the first termination body and the second termination body to form a chamber;
- and
- a second set of primary and secondary seals adapted to be fitted between the second termination body and the sleeve,
- wherein the second termination body comprises a first part and a second part;
- wherein the second set of primary and secondary seals is fitted in the first part between the second termination body and the sleeve;
- and
- a second test port in the first part of the second termination body to supply a second test fluid to a point between the second set of primary and secondary seals of the first part of the second termination body.
