Rotolock Valves, sometimes spelled “Rotalock” are service valves typically used in refrigeration systems. The actual Rotolock connection is a threaded connection that incorporates a Teflon Seal which is the main seal in preventing leaks in the connection. The primary uses of the valve include the ability to access the refrigeration system for charging and evacuation procedures. The valves are also very handy as they provide ease of removing equipment such as a compressor due to the threaded connection.
