Perfect fit for Big Blue filter
These o-rings fit the Pentair Big Blue filter much better than other brands I have bought. Other brands had a diameter slightly too big for the o-ring channel in the filter sump, making it difficult to seat them in the channel, which required multiple attempts to reattach the sump to the top of the filter to get the assembly leaktight. These o-rings were just right. They seated totally within and against the outside wall of the filter sump o-ring channel, so when the sump was reattached to the top the filter it was leaktight on the first try.
