Rated 4 out of 5 by from 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.

Rated 1 out of 5 by from 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

Asked by: Bart123
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?

Asked by: milankoivich
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.
