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. ## Features - Package Content:2pcs 50mm 1/2inch NPT Thermowell. - Size:Thread and Rod Length: 50 mm/ 2 inch; Pipe Internal Diameter: 6mm/ 0.24 inch; Pipe External Diameter: 8 mm/ 0.31 inch; Rod Diameter: 8 mm/ 0.31 inch; Total Size: 82*21 mm/ 3.2*0.83 inch(L*W). - Material:Made of high quality stainless steel.

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. ## Frequently Bought Together - Meprotal 2pcs 1/2 Inch NPT Thermowell Weldless Stainless Steel Temperature Sensor Thermowell with Plastic Cap for Homebrew Brewing Beer Fermenter 50mm/2'' Length - FERRODAY Stainless Steel 1/2” NPT Weldless Bulkhead Strong Gaskets Easy to Use Bulkhead Fitting for Homebrew Kettles Beer Rain Barrel Weldless Bulkhead Aquarium Adapter 1/2 Weldless Bulkhead Fitting - heyous 2pcs 1/2 Inch NPT 100mm Thermowell Stainless Steel Thermowell with Nylon Cable Gland for Temperature Sensors --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.kw/products/427169342-2pcs-1-2-inch-npt-thermowell-weldless-stainless-steel-temperature](https://www.desertcart.com.kw/products/427169342-2pcs-1-2-inch-npt-thermowell-weldless-stainless-steel-temperature) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-18*
