REBUILD: GURU DL

#480-04-87 Reb DL 2.1 -40 Type S 40F Reb. Cartridge, Hex & Lanyard

2.1 Plug An automatic freeze-out plug with one important difference: The stainless steel GURU Cartridge releases itself from its body at a pre-set water temperature (35°F or 40°F), rather than being forced out by the tremendous pressure of expanding ice. This provides almost a full one inch bore to rapidly drain the typical locomotive before damage can occur.

Resetting and rearming the GURU DL 2.1 Plug is easily accomplished by simply reheating the cartridge and utilizing the slotted actuator feature along with the GURU Flag and Clip. This feature prevents the GURU Plug from triggering open while refilling the cooling system with cold water and provides highly visual indicator of a deactivated GURU valve.
