Which fitting is commonly used in refrigeration to ensure a secure connection?

Compression fittings are widely used in refrigeration systems due to their ability to create a tight, leak-proof seal without the need for welding or soldering. The design of a compression fitting allows it to be easily installed and removed, making maintenance and repairs more convenient. In refrigeration applications, where connections must withstand high pressure and temperature variations, compression fittings are ideal as they provide a secure and robust joint that can accommodate these stresses.

Additionally, compression fittings are versatile and can be found in various materials, ensuring compatibility with different refrigerants and system components. This makes them a preferred choice among technicians for establishing reliable connections in refrigeration lines. The ease of installation and reliability under varying conditions underscore why compression fittings are a common choice in the refrigeration industry.
