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
