What is typically used to connect different refrigeration components securely?

Compression fittings are typically used to connect different refrigeration components securely because they provide a reliable seal and are designed to accommodate the expansion and contraction that can occur with temperature fluctuations in refrigeration systems. These fittings are made to allow for a snug fit between pipes or tubes, ensuring that refrigerants do not leak and that the system operates efficiently.

The design of compression fittings allows for ease of installation and maintenance, as they can be easily unscrewed if adjustments are needed without the risk of damaging the components. In refrigeration applications, maintaining leak-proof connections is crucial for system performance and safety, making compression fittings a widely preferred choice among professionals in the field.

Other options like welded joints are more permanent and typically used in situations where a solid and lasting connection is required, but they do not offer the flexibility of being reconnected or adjusted easily. Rubber bands and tape lack the necessary strength and reliability for secure connections under the pressures and conditions present in refrigeration systems, which underscores why compression fittings are the optimal choice.
