A Hoshizaki 420915-11 Reducer/Fitting connects tubing at the expansion valve to maintain proper refrigerant flow within the unit.
The reducer/fitting directs refrigerant flow between the copper tubing and expansion valve so the refrigeration system can maintain proper pressure and temperature control. Its copper construction and precise fitting design support secure connections, efficient heat transfer and reduced risk of leaks in display cabinets and reach-in refrigerators.
The reducer/fitting may need replacement if the equipment shows inconsistent cooling, unstable refrigerant flow or reduced temperature control during operation. Physical signs can include corrosion, cracks or loose connections and environmental signs may include refrigerant residue, moisture buildup or frosting near the fitting area.
