Using the same face-sealing o-ring design as our popular weldless bulkheads, this thermowell was designed from the ground up to be a weldless thermowell. 12" penetration into the vessel, with a .27" ID to fit most digital controller/thermometer sensors. Saves the expense of adding a weldless bulkhead first, then adding a thermowell to that. Includes 2 silicone o-rings and locknut. 304 stainless.

New 12" Version!

requires 1/2" hole and has 1/2" X 20UNF threads.  Also requires a wrench or channel locks that can grab a 1-1/8" hex.
