  • first and second fittings, each of said first and second fittings having a tapered bore and an orifice at an end of said bore, said orifice being positioned on an axis of said fitting and on a surface of said fitting;

    a first capillary tube inserted into said tapered bore of said first fitting;

    a second capillary tube inserted into said tapered bore of said second fitting;

    an end of said first capillary tube being spaced apart from said orifice of said first fitting and an end of said second capillary tube being spaced apart from said orifice of said second fitting, said orifice of said first fitting having a diameter no greater than an outside diameter of said first capillary tube and said orifice of said second fitting having a diameter no greater than an outside diameter of said second capillary tube;

    a sleeve positioned so as to guide the surface of said first fitting into contact with the surface of the second fitting such that the orifice of the first fitting is aligned with the orifice of the second fitting, the contact between the surfaces of the first and second fittings creating a gas tight seal around said orifices.
