ABSTRACT:
A capillary tube of long length insertable into a distal end of a process tube from a compressor of a refrigeration unit has a Schraeder fitting attached to a distal end of the capillary tube to charge the compressor, after charging the compressor the proximal tip of the capillary tube can be cut from the capillary tube and fitting and the capillary tube tip can be inserted into a swage block which forms a capillary sealing anvil and a handle with a threaded shaft and capillary tip sealing tip can be threaded into a perpendicular shaftway to seal the capillary, thus reducing the number of fittings that a refrigeration unit compressor charger must carry from refrigeration unit to refrigeration unit.
