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.

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.

Will work as soon as the temps get above freezing here in NW Ohio.I got them to put in a wireless sensor for my outdoor furnace.

When I plumbed these into my radiant floor heating system they leaked despite copious amounts of Teflon Tape and pipe joint compound. They tightened all the way into the 3/4" to 1/2" brass bushing so didn't seem to have the proper taper that NTP fittings use. They leaked and I had to replace them temporarily with a plug.
