Made from 316 stainless steel, these thermowells are made using the same process as my stainless steel temperature probe ends. The end is spun shut and then sealed with a TIG weld. The entire body is then polished for easy cleaning and the perfect sanitary surface. Other thermowells on the market are just crimped closed and then sealed with a weld, leaving a jagged rough surface. We've even seen a few out there that they didn't even bother to clean the markings off the tubing!
This is a smaller diameter version for a tighter fit. The ID is .25" nominal so any sensor with an OD of less than .25" should fit. Note that due to a compounding of tolerances, some sensors might require some shaving, sanding or fine tuning to fit, but the tighter fit and tolerance will provide a faster reaction time to the sensor.
ID = .25"
