Works like the original, but outrageously expensive. I might be looking for a cheaper alternative next time.

First package arrived empty! I called the only number that was available and it was a direct line to Pentair. They were of ZERO help and told me I have to contact Amazon. The absolute worst customer support I’ve come across in a very long time! I’ll start using aftermarket parts, I won’t be ordering Pentair parts for anything. But it did fit like it was supposed to so at least they got that right…

This was exactly the size needed. Doesn't leak at all, even under pressure from the pump. I bought this to replace my old cap after I broke it with a rubber mallet trying to re-seal the filter assembly. MUCH cheaper than replacing the entire filter cap.
