Lantern rings are a critical component of braided packing, providing additional support and improving the overall sealing performance. Lantern rings are circular devices that are inserted into the braided packing to provide additional support and prevent extrusion under high pressures.
Lantern rings are installed between braided packing to act as a spacer, or to divide the packing into different sections, which helps to prevent extrusion or twisting of the packing under high pressure. Lantern rings can also provide a channel for coolant or lubricant to flow through, which can help to control the temperature of the packing and reduce wear and tear.
