What is the temperature rating of the potting used around the wires.
Thank you for your inquiry. The integrity of the seal is limited to 120C.

do you sell a crimp or tool to attach the 2 different wire types of the type k thermocouple wire to make a good junction that will be reliable connection going hot and cold and condensation? Or do you provide a service to spot weld the ends together?
Hi Tom C,
Thank you for the inquiry. We do not offer tool for making junction other then our welder. We do not offer welded option. Suggested method of termination and use is to use a terminal block or connector to mate to a pre welded wire or probe style TC.
Best regards

Can this connector be used above 120C if there's no pressure? what limits the temp rating if wires are good for 200C?
The integrity of the seal is limited to 120C but if your not concerned about leaking in Vacuum or Pressure it should be able to be used above 120C. Omega would not guarantee the product used outside the specified temperature range.
