I agree. Do not use loctite with plastic parts. Period. I never did that before and never will again. It seems (from what I have subsequently read on the internet) that it can both degrade PVC plastic as well as expand as it dries. It is not intended for plastic. Now I know.

This might explain the 'immediate' failure of handle #2. Although, as you can see from the photos, the loctite did not even have enough time to dry as it spilled over to the area around the base when it broke. Unsure how quickly it can degrade PVC but if it was the cause, it was almost immediate.

I did not however use any loctite on handle #1 (see photos, no loctite), That handle lasted about a week or two.
