A brass thermowell with hex nut and long stem – the reach of a long stem with the installation convenience of a hex nut. Brass threads make up smoothly and resist corrosion on the fitting side of the wall.
Function and Design
A thermowell looks like the simplest item in a catalogue and is often the most demanding to make consistently. Tolerances that matter are confirmed with capability data before the thermowell is quoted.
What Makes It Work
- Hex dimensions are inspected, so torque does not deform the flats.
- Long stems are checked for straightness along the full length, because a bowed well reads the wrong part of the pipe.
- The listing shows the family; dimensions and features come from your drawing.
- Material: brass (H62 / H65) for the thermowell, with material certs issued together with the dimensional report.
- Process: the thermowell is a deep drawn shell with machined seats and threads where the print calls for them, stem length held to the print.
- Finish: No catalogue finish: the thermowell surface is agreed on the drawing and confirmed at sample approval.
- Size: Final dimensions of the thermowell to your drawing; this page shows the family, your version is quoted from the print.
- Custom: OEM/ODM: send the thermowell drawing, quotation comes back with manufacturability notes.
Where It Is Used
Production volumes of this part run in household appliance thermometers, HVAC and refrigeration sensors, NTC and PT100 probe assemblies.
Our Production Advantage
Drawn shells are stress-relieved before critical faces are machined. Threads are gauged, sealing faces are checked, and the first article report travels with the batch.
