Thanks for posting that sprkplug. I would have only thought of an old school way with a fitting with seals on each side (like we use on big water tanks). Sometimes it is just a matter of knowing what is available to do the job.
I still like to just go through and browse a hardware, electric supply or plumbing store. Not that I need any of the stuff, but sometimes just knowing what is available that I might never realize existed that I MIGHT need some day.
