Description

Refrigeration couplings are essential components in refrigeration systems that allow for the transfer of refrigerant between different parts of the system. These couplings can be found in a wide range of applications, from commercial refrigeration systems to residential air conditioning units.

Another important consideration when it comes to refrigeration couplings is the type of refrigerant being used. Different types of refrigerant have different properties and may require specific types of couplings in order to function properly. For example, some refrigerants may require a coupling with a larger diameter or a different shape in order to accommodate their specific characteristics.
