What I think you're looking for is a bulkhead fitting like this, usually installed so the threaded part is facing the inside but you could mount it the other way and get a cap that screws onto it.
You could also use something like this a cable gland but grab a closed end sealing nut to make it into a cap.
I just bought these and they're threaded on both sides so that what you linked to (or these which I also bought) should fit. I put them on some 5gal buckets and the seal is working great. Pretty happy with the setup so far :)
I think you're looking for bulkheads (like this https://www.amazon.ca/dp/B0002DKANM). Usually they are set up for either glued or threaded PVC pipe. If you go with threaded bulkheads, you can get barbed adapters (https://www.homedepot.ca/product/1000117559) so you can use flexible tubing with them. Make sure to use teflon thread tape on all threaded joints or they will leak.
Keep in mind that bulkheads only work on flat surfaces, not curved. If you want to pass pipe through a curved surface, you can use a uniseal.
