I am working on a project that requires a removable, sealed, connection between copper tube and pvc (or other low-cost rigid tube/pipe/rod). The connection needs to be as flush as possible while not pulling apart. The best I could think of is threading schedule 80 pvc pipe and type K copper tubing for a direct screw-on connection between two pieces, but I am uncertain if this will work and whether it would stand up to repeatedly screwing it on and off. If it could work, what copper tube size and pvc pipe (including CTS vs standard) size combinations should I get to thread them with copper as female and pvc as male? The OD of both pvc and copper should be about the same as 3/4" copper tube, and the ID of the copper can't be less than 0.67" (ID of the pvc doesn't matter).

For a little background, this project is for graduate research where I will be placing temperature loggers into the ground at various depths (at each copper junction) up to about 3' deep.

Thanks for any help.
