Can bell and spigot fittings be used in refrigeration systems?

1. True

2. False

3. Only in certain applications

4. Only if approved by code

The correct answer is: False

Bell and spigot fittings are primarily designed for use in water and drainage systems, and they are not appropriate for refrigeration systems. Refrigeration systems typically require fittings that can withstand the specific pressure and temperature conditions associated with refrigerants. Using bell and spigot fittings in these scenarios could lead to leaks, failures, or safety hazards due to the inability to properly seal the connections under the pressure that refrigeration applications require. In refrigeration applications, fittings must be compatible with the refrigerant being used, ensure tight seals to prevent leaks, and be constructed from materials that can handle the thermal cycling that occurs within these systems. Therefore, the assertion that bell and spigot fittings can be used in refrigeration systems is not correct.
