Ceramic Thermocouple
The product quality is great and works for the most part. Unfortunately, the 24 inch section I purchased arrived broken in 3 pieces. Now I know the shipping company probably stacked a refrigerator on top of this box but the packaging could have been better to protect the fragile material inside. In comparison, I have purchased steel from suppliers who package tough steel bar better than this thermocouple was packaged. This is why I only gave 4 out 5 stars.

It's not 0.25" OD. It's 0.26" ... doesn't fit.
I purchased the PTRA-31614-24 which is sold as a 0.25" OD, but it won't fit into any of my 0.25" hardware. I measured with calipers and it's 0.26"?
Can't use them.
