The label say it works for LT-500P and 5231JA2002A. I used it to replace a 5231JA2002A, and it didn't work at all. The leak wasn't a trickle, it gushed. I tried all three, all three leaked. I tried installing the filters multiple times each, using little and lots of force to no effect. I finally put the old one back in, no leaks, worked the first time.

This COULD work for a LT-500P. But it defintely doesn't work for 5231JA2002A.
