This Thermocouple (48"L) replaces Nieco 18861. It generates the millivolt signal that tells the gas valve the pilot is lit. Replacement is usually called for when you are seeing a pilot that lights but will not stay lit once the knob is released, or a burner that drops out during a cycle.
It also cross-references 2 manufacturer part numbers. Check the number on the part you are replacing, or your unit's model number, against the lists below before ordering.
Supplied as a single replacement unit.
