Rotolock valves
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.

FlareSeal
The FlareSeal® was developed specifically for the HVAC/R industry. The seal protects against the primary area of flare leaks on the sealing surface. FlareSeal® fits all common SAE flare connections for the industry. It not only provides a long term leak-free connection on new installations or products, but it also can be used to stop weeping connections in existing systems. There is a general industry push towards leak-free systems and the elimination of leaks on existing equipment. Currently, the weak links in the system are the flare connections … but no more! The flare connection is preferred for components for ease of service but has slowly gone the way of sweat connections due to the leak issues and liability associated with loss of refrigerant. The Multi-Ring-Seal by FlareSeal® allows the best of both worlds in a flare connection, allowing for serviceable components while maintaining a permanent leak-free connection. FlareSeal® can even be used to repair a small existing leak!
