Industrial Thermowell 316SS 1-1/4-18
This industrial thermowell is manufactured from 316 stainless steel for corrosion resistance in demanding process environments. It suits plant engineers and maintenance teams who need a reliable sensor housing for temperature measurement in piping systems. The straight internal thread and NPT process connection match common industrial fittings. Buyers who require flanged or sanitary connections will need a different thermowell style.
Thermals and Pressure Containment
The 316 stainless steel construction withstands elevated process temperatures and pressures typical of steam, oil and chemical service. A 0.44 in bore diameter accepts standard temperature sensors while maintaining structural integrity. The 0.62 in shank diameter and 18.5 in socket length provide mechanical strength under flow-induced vibration. No active cooling or power is required for normal operation.
Installation and Build Integration
The thermowell installs into a 1 in NPT process tapping with an 18 in stem length and 17 in insertion depth. The 1-1/4-18 straight internal thread accepts compatible thermowell sensors or thermometers directly. A 0.5 in wrench allowance permits standard tool engagement during assembly. It frees up sensor selection by accommodating any probe that matches the internal thread and bore dimensions.

Questions about this item
How do I install the Zoro Select 24C454 thermowell and which step is often missed?
Thread the 1 in NPT process connection into the piping and tighten using the 0.5 in wrench allowance; the step often missed is confirming the 1-1/4-18 internal thread matches the sensor before final torque.
What maintenance or replacement will the 316 stainless steel thermowell need over time?
Inspect the 0.44 in bore and 0.62 in shank periodically for corrosion or erosion; replace the unit if the 17 in insertion length shows pitting or the 18.5 in socket length threads are damaged.
What limit appears first when the thermowell runs continuously in a high-flow process?
The 0.44 in bore diameter and 0.62 in shank diameter set the velocity limit; sustained flow beyond the material’s wake-frequency rating will cause vibration fatigue first.
