The probe adapter is a 1/2" or 3/4" NPT threaded on either end for mounting to the housing, and a conduit head. The ID thread is available to fit the 2 common eddy probe thread sizes. For particularly long probes an optional deep conduit head is available. The CMCP4190 is made of 316 Stainless Steel.
