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…

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

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.
