ABSTRACT:
A sealing fixture in combination with a cap member provides a fluid-tight compression seal between an elastomeric septum and a tubular body. The septum is disposed transversely on a first end of the sealing fixture, which is of cylindrical configuration with an axial bore. A second end of the sealing fixture fits over the tubular body. The cap member covers the septum by being screwed down over a threaded portion of the outer wall of the sealing fixture. An aperture is provided in the cap member through which an injection device can be inserted to puncture the septum so as to deliver a quantity of fluid to, or to remove a quantity of fluid from, the tubular body via the bore in the sealing fixture. An outer wall portion of the sealing fixture adjacent the first end thereof is tapered inwardly to form a sharp junction with an inner wall portion of the sealing fixture. This inner wall portion adjacent the first end of the sealing fixture is parallel to the axis of the bore. As the cap member is screwed down over the first end of the sealing fixture, the sharp junction cuts into the septum. An edge portion of the septum overhanging the junction is compressed between the cap member and the tapered outer wall portion of the sealing structure, thereby providing a compression seal while leaving the central portion of the septum relatively stress free.
