Bard 9021-080 - Oil line locknut

Bard part number 9021-080 is an OEM oil line locknut used in the refrigerant and compressor oil management portion of certain Bard wall mounted HVAC systems. This locknut helps secure the oil line connection to reduce the chance of loosening from vibration and normal service movement, which is important for maintaining proper oil return and reliable compressor operation. When replacing it, match the part number exactly and confirm the oil line fitting style and thread requirements for your specific Bard model and revision, since oil line hardware can vary between unit families and production changes.
