Thermowell Machined

The ACI/M2.5" M4" and 8" thermowells are made of A.I.S.I. 300 series stainless steel to ensure long lasting reliability and stability. The wells are machined from solid bar stock using the most modern CNC machines. The bore is smooth, true, accurately centered, and precisely sized for 0.250" O.D probes. The thermowells are machined from one piece of stainless steel to avoid the weak point inherent in a weld. The well will be able to withstand rapid temperature changes without any degradation in its' mechanical structure. The precision bore gives excellent thermal conductivity from the well to the temperature sensor.

If preferred, thermal grease may be used with all of the thermowells. ACI offers the thermal grease in both a silicone and non-silicone compound. The silicone compound is available in a 8 oz. tube and the non-silicone compound is available in a 2 oz. tube.
