The present invention is a connector which connects a first control line in a downhole well tool to a second control line. The connector may include a main body having a longitudinal bore therethrough, a tubular extension threadably secured within a mounting bore in the well tool, and a metal seal ring disposed between a shoulder on the tubular extension of the main body and having an outer conical surface engaged with a conical surface of the mounting bore. The connector may also include a sealing sleeve having a longitudinal bore including a first conical surface adjacent a first end of the sealing sleeve and a second conical surface adjacent a second end of the sealing sleeve; a first ferrule, a second ferrule, and a third ferrule, each being an annular member having an outer conical surface and disposed within the longitudinal bore of the main body. The first ferrule is disposed about the second control line, the outer conical surface of the first ferrule is engaged with the first conical surface on the sealing sleeve; the second ferrule is disposed about the first control line, the outer conical surface of the second ferrule is engaged with the second conical surface on the sealing sleeve; and the third ferrule is disposed about the first control line, the outer conical surface of the third ferrule is engaged with a first conical bore in the main body. A tubular spacer member can be disposed about the first control line and between the second and third ferrules. The connector can further comprise a retaining fitting having a longitudinal bore therethrough and threadably secured within the longitudinal bore of the retaining fitting and the longitudinal bore on the sealing sleeve. |
