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.

Hello. What is your recommended bonding method for attaching metal fittings to these ceramic tubes? Thanks
Omega use's its CC HIGH TEMP Cement to bond the metal fittings to the tubes.

For the Alumina tube with 0.187 inch inner diameter (PTRA-31614-18), does it work with the KQIN-316U-18 thermocouple, which has a 0.187 inch outer diameter? Is there enough tolerance so that the thermocouple can be inserted with no issues?
It is recommended to go one size larger on the id as the tolerance of probe and tube would not be enough to guarantee insertion.
