Abstract:
An apparatus for protecting a refrigeration line against crimping, the apparatus comprising:a) a length of solid hollow tubing, with a first end of the tubing extending into an inner space of a building wall, and a second end of the tubing extending out of the exterior of the building wall; b) a length of flexible refrigerant line running which extends through the building wall space through an opening in the tubing and extends out from an outer end of the tube; c) an etched line along the wall portion of the tube, positioned at a point so that the etched line may serve as a means for cutting an exterior portion of the tube from the tube body in the event the refrigerant line is crimped so as to expose a greater portion of uncrimped refrigerant line but may be cut and spliced as needed.
