When replacing valve plates or service valves, what should be used to lubricate the gaskets?

Using refrigeration oil to lubricate gaskets when replacing valve plates or service valves is essential for ensuring an effective seal and maintaining the functionality of the refrigeration system. Refrigeration oil is specifically formulated to work with the materials commonly found in these systems, providing both lubrication and compatibility with refrigeration components.

This type of oil helps conform the gaskets to the sealing surfaces, reducing the risk of leaks and wear on both the gaskets and the components they are sealing. Additionally, refrigeration oil can withstand the varying pressures and temperatures typical in refrigeration applications, making it a reliable choice.

In contrast, water is not suitable because it may promote rust and corrosion in metal components, oil-based lubricants may not be compatible with refrigerants, and general-purpose grease can lead to improper sealing or chemical reactions with system materials. Therefore, using refrigeration oil ensures the proper operation and longevity of the system by promoting an effective and lasting seal.
