<p>I did some more searching and DING, found plastic bulkhead fittings that will work. I wasn't originally thinking of these as I thought all caps were rounded. Then I found the "socket caps" which give a nice flat surface but then forgot to go back to bulkhead.</p>
<p>Thanks all!</p>

- Have you looked at a bulkhead fitting through the cap? Pretty clean
looking, pretty short, no questionable threads in PVC. Ends with 1/4² M,
not F, if that¹s an issue.
