PTFE Lantern rings serve three purposes: protection, cooling and lubrication. They protect the stuffing box and the installed packing by providing an access point for flush water. If process fluids or other contaminants enter the stuffing box and are not removed by flush water, several problems occur, including:
• damaged or destroyed packing
• shaft or sleeve damage
• stuffing box wear

A lantern ring also gives the stuffing box an outlet to assist with cooling. It allows the system to avoid being completely closed off and assists in mitigating overheating. The final lantern ring purpose is lubrication. Compression packing causes friction along the shaft and stuffing box walls or casing.
Fluid entering through the lantern ring lubricates the packing. The liquid reduces friction, limits the wear of the machine’s parts and decreases heat within the system.
