I am using it for homebrewing, to put the probe of my temperature controller safely into our fermentation bucket. Making 5-gallon batches in a 5-gallon bucket, the length of this thermowell is very helpful to make sure that the probe touches the liquid.So far, it seems to be doing this very well and we get seemingly accurate readings!As others have noticed (and the reason I knocked off one star), the actual thread on the top of the thermowell is not really long enough to fit the entire securing nut, when you account for the gaskets and the material that the thermowell is poking through.Since an absolutely perfect seal is not necessary (because no water touches the attachment end of the thermowell) I decided to simply not use one of the gaskets. But for a perfect air/watertight seal, you may consider looking at other products. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Works Fantastically! Thermowell on Plastic. *by G***N on Reviewed in the United States 🇺🇸 on November 18, 2022* If you're looking to Incorporate a thermowell into the lid of a plastic fermenting bucket look no further.Get yourself a 3/4” hole driving bit and you’ll be in business. The gaskets and threaded nut ensure a great seal. I purchased the 200mm length which is more than long enough for both my 6.5 gallon wider diameter bucket and my 5 gallon tall, skinny bucket. This also worked perfectly for my 5 gallon glass carboy. Buy a longer length if you’re worried about contact with wort.I use this with a warming sleeve connected to a temperature probe control and its amazingly effective. If you’re a home brewer, you know all too well there are enough variables you can’t control; temperature doesn’t have to be one of them!Purchase with confidence; this product does what it says it will do, which is rare these days! ### ⭐⭐⭐⭐ 4.0 out of 5 stars Retaining nut doesn't have an O-ring groove *by J***K on Reviewed in the United States 🇺🇸 on October 14, 2019* This item is well made and my temperature probe fits perfectly, but I couldn't get it to stop leaking. The retaining nut is flat with no groove for the O-ring; when the nut is tightened, the O-ring is crushed and doesn't seal properly. I had a spare grooved nut which solved the problem with one of the two items that I ordered. --- ## 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.vn/products/137746954-1-2-inch-thermowell-weldless-with-screw-nut-gasket-stainless](https://www.desertcart.vn/products/137746954-1-2-inch-thermowell-weldless-with-screw-nut-gasket-stainless) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-22*
