## Description

desertcart.com: Meprotal 2pcs 1/2 Inch NPT Thermowell Weldless Stainless Steel Temperature Sensor Thermowell with Plastic Cap for Homebrew Brewing Beer Fermenter 50mm/2'' Length : Industrial & Scientific

Review: Not weldless as described - otherwise OK but not great - As noted in title, the well tube is welded onto the threaded base. Decent workmanship but the steel in the tube has obviously had a huge thermal cycle. Product appears to be SST but there is corrosion inside the tube, should be fine after cleaning. Measured the threads and they are tapered per NPT spec but are the minimum size range and fit sloppy for the first few turns into a fitting. Have not tested for leaks yet. Would return and replace if I didn't have a need for them soon.
Review: Good Quality, Fit, Value - Works just as described. As with all stainless steel items, properly clean and passivate before use to prevent rust. Yes, stainless can rust without proper care.

### ⭐⭐⭐⭐⭐ Review
*by V***L on December 9, 2025*

Compré estos termopozos para instalar el sensor de temperatura en la tubería de mi tina de agua fría (Cold Plunge) casera. Lo mejor: • Instalación: La rosca de 1/2" NPT encajó perfectamente en la "T" de PVC que usé en mi sistema de filtrado. Con un poco de cinta teflón, selló a la primera y no ha goteado ni una gota, lo cual era mi mayor miedo. • Compatibilidad: Mi sonda de temperatura (uso un controlador tipo Inkbird) entró perfectamente dentro del pozo. • Material: Al estar en contacto constante con agua fría y a veces con desinfectantes, el acero inoxidable es vital. Se ve muy resistente y de buena calidad. Conclusión: Si estás armando tu propio sistema de enfriamiento, estos termopozos son esenciales para no tener cables sueltos dentro del agua. 100% recomendados.
