Hello, does the thermocouple wire come with a connector, and if so, which type of connector?

Asked by: wenv1
The Thermocouple wire runs through the fitting which is filled with epoxy. Each wire has stripped leads and no connector so this would be added by the customer.

Hello. Is the 48 in thermcouple length split equally on both sides of the fitting? Is customization available to shift the wire to have, say, only 6 in on the thread side? Thanks.

Asked by: hyaaq
There is actually 48&quot; on each side of fitting (a little over 96&quot; total). No customer variations are available.

Hi, Can I use this feedthrough for glove box installation? Do I need an extra bolt for the other side to fix it on the glove box wall? If yes, do you have such a matching bolt? Thank you,

Asked by: somayeh
The fitting is a 1/2 NPT male tapered thread. It's designed to be installed into the matching female NPT connect. Typical application would be a pressure vessel with the female mating fitting installed on it. The thread engagement into the female fitting is nominally only the first 4 or 5 threads. You would typically use &quot;plumber's tape&quot; to seal the threads. There is no type of nut available that has NPT threads
