Stainless steel thermowell, 18 inch stem, threaded process connection

Value Brand

Value Brand 24C467 Bimetal Thermowell 316SS 1/2 NPSM 18 in

SKU CH-6QD3-Z3X9M

Protects temperature sensors with an 18-inch 316 stainless steel thermowell featuring a 1/2 NPSM internal thread and 3/4 NPT process connection

  • Product typeEnvironmental & Mechanical
  • 316 stainless steel resists corrosion in harsh environments
  • 18 inch stem reaches deep process points
  • 1/2 NPSM internal thread fits standard bimetal thermometers
  • 3/4 NPT process connection seals directly into piping
  • 26 inch bore matches common sensor diameters

Industrial temperature protection

The Value Brand 24C467 bimetal thermowell shields sensors in process piping using 316 stainless steel. It suits plant engineers and maintenance crews who need reliable immersion for 0.26 in bore thermometers.

Sustained process exposure

The 316 stainless construction resists corrosion during continuous immersion at the 16 1/2 in insertion depth. The 0.5 in shank diameter maintains structural integrity under steady flow and pressure cycles.

Installation verification

Confirm the 3/4 in NPT process connection matches your piping and that the 1/2 NPSM internal thread fits the sensor. Check the 18.25 in socket length and 0.75 in wrench allowance against available clearance.

Questions about this item

Does the 0.26 in bore diameter affect heat transfer response time during continuous monitoring?

The 0.26 in bore diameter provides a direct path for the sensor element, allowing process temperature to reach the bimetal element efficiently for steady readings during extended use.

What thread sealant or fitting is required for the 1/2 NPSM internal connection?

The 1/2 NPSM internal thread accepts a compatible male NPSM fitting; apply thread sealant rated for the process media to ensure a leak-free seal at the 3/4 in NPT process connection.

Will the 18.25 in socket length fit through existing 3/4 in NPT process piping without modification?

The 18.25 in socket length with 16 1/2 in insertion depth is designed for standard 3/4 in NPT process connections, matching typical pipe fitting dimensions for direct installation.
