Remote oil filter adapter unscrewing when cold

[N2BUICK]

Odd problem checking to see if anyone has experienced and what they did to correct.
The remote oil filter adapter will unscrew enough to start leaking oil.
This is primarily when its cold. Oil gets thick and the two rubber lines tend to straighten out, spinning the adapter enough to leak.
Since I rarely drive the car, especially rare when its cold. Don't ask how long this has been going on.
Anyone else had issues like this?

Known problem.
AIRC, there's a fatter o'ring used as a fix.
I think I got a box of them from a NAPA store.
A search should show the link. Here's 1.
