Delfield 0074058-S Freezer Capillary Tube R404A 4004048

The Delfield 0074058-S Freezer Capillary Tube measures refrigerant flow from the high-pressure side toward the evaporator within compatible refrigeration equipment. Its narrow internal passage creates a controlled pressure drop as liquid refrigerant travels through the tubing, regulating flow into the cooling circuit. This part is installed between the condenser-side liquid line and evaporator inlet, routed at the designated connection points within the cabinet. The 4004048 assembly uses small-diameter tubing suited to metering R404A refrigerant in the associated circuit. Its connections integrate with adjoining refrigeration lines, allowing refrigerant to pass through the restricted passage before reaching the evaporating section.
