Nuova Simonelli High Limit Boiler Thermostat - 135°

135°C 16A 250V. Flat meeting surface with a circular mounting bracket for two screws (not included).

Thermal paste (or "grease") aids heat transfer between the switch and contact surface by filling in microscopic imperfections in the metal surfaces. It is especially useful for pipe mount applications.

A key characteristic of this synthetic thermal grease is it's long-term material stability. That means it won't harden, dry out, or melt in normal industrial use.

Smear some paste on the sensing head of the thermostat switch prior to bolting or clamping down. (Not to be used as a glue.)
