The Bard 800-0387 orifice assembly is an OEM refrigerant metering component used in select Bard wall-mounted air conditioners and heat pumps to help control refrigerant flow through the system for stable cooling performance and proper coil operation. A correctly sized orifice is critical for maintaining normal suction and head pressures, protecting the compressor, and preventing symptoms like poor capacity, icing, or nuisance trips when the original metering device is restricted or damaged. Because orifice sizing and application can vary by model and serial range, confirm fit by matching your unit model/series and the parts list from the appropriate Bard service manual before ordering, then replace using standard refrigeration best practices including leak checking and proper evacuation.
